Bayes Theorem
A theorem in probability theory named for Thomas Bayes (1702-1761). In epidemiology, it is used to obtain the probability of disease in a group of people with some characteristic on the basis of the overall rate of that disease and of the likelihood of that characteristic in healthy and diseased individuals. The most familiar application is in clinical decision analysis where it is used for estimating the probability of a particular diagnosis given the appearance of some symptoms or test result.

Bayesian inference on biopolymer models. (1/6254)

MOTIVATION: Most existing bioinformatics methods are limited to making point estimates of one variable, e.g. the optimal alignment, with fixed input values for all other variables, e.g. gap penalties and scoring matrices. While the requirement to specify parameters remains one of the more vexing issues in bioinformatics, it is a reflection of a larger issue: the need to broaden the view on statistical inference in bioinformatics. RESULTS: The assignment of probabilities for all possible values of all unknown variables in a problem in the form of a posterior distribution is the goal of Bayesian inference. Here we show how this goal can be achieved for most bioinformatics methods that use dynamic programming. Specifically, a tutorial style description of a Bayesian inference procedure for segmentation of a sequence based on the heterogeneity in its composition is given. In addition, full Bayesian inference algorithms for sequence alignment are described. AVAILABILITY: Software and a set of transparencies for a tutorial describing these ideas are available at http://www.wadsworth.org/res&res/bioinfo/  (+info)

Genetic determination of individual birth weight and its association with sow productivity traits using Bayesian analyses. (2/6254)

Genetic association between individual birth weight (IBW) and litter birth weight (LBW) was analyzed on records of 14,950 individual pigs born alive between 1988 and 1994 at the pig breeding farm of the University of Kiel. Dams were from three purebred lines (German Landrace, German Edelschwein, and Large White) and their crosses. Phenotypically, preweaning mortality of pigs decreased substantially from 40% for pigs with < or = 1 kg weight to less than 7% for pigs with > 1.6 kg. For these low to high birth weight categories, preweaning growth (d 21 of age) and early postweaning growth (weaning to 25 kg) increased by more than 28 and 8% per day, respectively. Bayesian analysis was performed based on direct-maternal effects models for IBW and multiple-trait direct effects models for number of pigs born in total (NOBT) and alive (NOBA) and LBW. Bayesian posterior means for direct and maternal heritability and litter proportion of variance in IBW were .09, .26, and .18, respectively. After adjustment for NOBT, these changed to .08, .22, and .09, respectively. Adjustment for NOBT reduced the direct and maternal genetic correlation from -.41 to -.22. For these direct-maternal correlations, the 95% highest posterior density intervals were -.75 to -.07, and -.58 to .17 before and after adjustment for NOBT. Adjustment for NOBT was found to be necessary to obtain unbiased estimates of genetic effects for IBW. The relationship between IBW and NOBT, and thus the adjustment, was linear with a decrease in IBW of 44 g per additionally born pig. For litter traits, direct heritabilities were .10, .08, and .08 for NOBT, NOBA, and LBW, respectively. After adjustment of LBW for NOBA the heritability changed to .43. Expected variance components for LBW derived from estimates of IBW revealed that genetic and environmental covariances between full-sibs and variation in litter size resulted in the large deviation of maternal heritability for IBW and its equivalent estimate for LBW. These covariances among full-sibs could not be estimated if only LBW were recorded. Therefore, selection for increased IBW is recommended, with the opportunity to improve both direct and maternal genetic effects of birth weight of pigs and, thus, their vitality and pre- and postnatal growth.  (+info)

Bayesian mapping of multiple quantitative trait loci from incomplete outbred offspring data. (3/6254)

A general fine-scale Bayesian quantitative trait locus (QTL) mapping method for outcrossing species is presented. It is suitable for an analysis of complete and incomplete data from experimental designs of F2 families or backcrosses. The amount of genotyping of parents and grandparents is optional, as well as the assumption that the QTL alleles in the crossed lines are fixed. Grandparental origin indicators are used, but without forgetting the original genotype or allelic origin information. The method treats the number of QTL in the analyzed chromosome as a random variable and allows some QTL effects from other chromosomes to be taken into account in a composite interval mapping manner. A block-update of ordered genotypes (haplotypes) of the whole family is sampled once in each marker locus during every round of the Markov Chain Monte Carlo algorithm used in the numerical estimation. As a byproduct, the method gives the posterior distributions for linkage phases in the family and therefore it can also be used as a haplotyping algorithm. The Bayesian method is tested and compared with two frequentist methods using simulated data sets, considering two different parental crosses and three different levels of available parental information. The method is implemented as a software package and is freely available under the name Multimapper/outbred at URL http://www.rni.helsinki.fi/mjs/.  (+info)

The validation of interviews for estimating morbidity. (4/6254)

Health interview surveys have been widely used to measure morbidity in developing countries, particularly for infectious diseases. Structured questionnaires using algorithms which derive sign/symptom-based diagnoses seem to be the most reliable but there have been few studies to validate them. The purpose of validation is to evaluate the sensitivity and specificity of brief algorithms (combinations of signs/symptoms) which can then be used for the rapid assessment of community health problems. Validation requires a comparison with an external standard such as physician or serological diagnoses. There are several potential pitfalls in assessing validity, such as selection bias, differences in populations and the pattern of diseases in study populations compared to the community. Validation studies conducted in the community may overcome bias caused by case selection. Health centre derived estimates can be adjusted and applied to the community with caution. Further study is needed to validate algorithms for important diseases in different cultural settings. Community-based studies need to be conducted, and the utility of derived algorithms for tracking disease frequency explored further.  (+info)

Bayesian analysis of birth weight and litter size in Baluchi sheep using Gibbs sampling. (5/6254)

Variance and covariance components for birth weight (BWT), as a lamb trait, and litter size measured on ewes in the first, second, and third parities (LS1 through LS3) were estimated using a Bayesian application of the Gibbs sampler. Data came from Baluchi sheep born between 1966 and 1989 at the Abbasabad sheep breeding station, located northeast of Mashhad, Iran. There were 10,406 records of BWT recorded for all ewe lambs and for ram lambs that later became sires or maternal grandsires. All lambs that later became dams had records of LS1 through LS3. Separate bivariate analyses were done for each combination of BWT and one of the three variables LS1 through LS3. The Gibbs sampler with data augmentation was used to draw samples from the marginal posterior distribution for sire, maternal grandsire, and residual variances and the covariance between the sire and maternal grandsire for BWT, variances for the sire and residual variances for the litter size traits, and the covariances between sire effects for different trait combinations, sire and maternal grandsire effects for different combinations of BWT and LS1 through LS3, and the residual covariations between traits. Although most of the densities of estimates were slightly skewed, they seemed to fit the normal distribution well, because the mean, mode, and median were similar. Direct and maternal heritabilities for BWT were relatively high with marginal posterior modes of .14 and .13, respectively. The average of the three direct-maternal genetic correlation estimates for BWT was low, .10, but had a high standard deviation. Heritability increased from LS1 to LS3 and was relatively high, .29 to .37. Direct genetic correlations between BWT and LS1 and between BWT and LS3 were negative, -.32 and -.43, respectively. Otherwise, the same correlation between BWT and LS2 was positive and low, .06. Genetic correlations between maternal effects for BWT and direct effects for LS1 through LS3 were all highly negative and consistent for all parities, circa -.75. Environmental correlations between BWT and LS1 through LS3 were relatively low and ranged from .18 to .29 and had high standard errors.  (+info)

Thermodynamics and kinetics of a folded-folded' transition at valine-9 of a GCN4-like leucine zipper. (6/6254)

Spin inversion transfer (SIT) NMR experiments are reported probing the thermodynamics and kinetics of interconversion of two folded forms of a GCN4-like leucine zipper near room temperature. The peptide is 13Calpha-labeled at position V9(a) and results are compared with prior findings for position L13(e). The SIT data are interpreted via a Bayesian analysis, yielding local values of T1a, T1b, kab, kba, and Keq as functions of temperature for the transition FaV9 right arrow over left arrow FbV9 between locally folded dimeric forms. Equilibrium constants, determined from relative spin counts at spin equilibrium, agree well with the ratios kab/kba from the dynamic SIT experiments. Thermodynamic and kinetic parameters are similar for V9(a) and L13(e), but not the same, confirming that the molecular conformational population is not two-state. The energetic parameters determined for both sites are examined, yielding conclusions that apply to both and are robust to uncertainties in the preexponential factor (kT/h) of the Eyring equation. These conclusions are 1) the activation free energy is substantial, requiring a sparsely populated transition state; 2) the transition state's enthalpy far exceeds that of either Fa or Fb; 3) the transition state's entropy far exceeds that of Fa, but is comparable to that of Fb; 4) "Arrhenius kinetics" characterize the temperature dependence of both kab and kba, indicating that the temperatures of slow interconversion are not below that of the glass transition. Any postulated free energy surface for these coiled coils must satisfy these constraints.  (+info)

Iterative reconstruction based on median root prior in quantification of myocardial blood flow and oxygen metabolism. (7/6254)

The aim of this study was to compare reproducibility and accuracy of two reconstruction methods in quantification of myocardial blood flow and oxygen metabolism with 15O-labeled tracers and PET. A new iterative Bayesian reconstruction method based on median root prior (MRP) was compared with filtered backprojection (FBP) reconstruction method, which is traditionally used for image reconstruction in PET studies. METHODS: Regional myocardial blood flow (rMBF), oxygen extraction fraction (rOEF) and myocardial metabolic rate of oxygen consumption (rMMRO2) were quantified from images reconstructed in 27 subjects using both MRP and FBP methods. For each subject, regions of interest (ROIs) were drawn on the lateral, anterior and septal regions on four planes. To test reproducibility, the ROI drawing procedure was repeated. By using two sets of ROIs, variability was evaluated from images reconstructed with the MRP and the FBP methods. RESULTS: Correlation coefficients of mean values of rMBF, rOEF and rMMRO2 were significantly higher in the images reconstructed with the MRP reconstruction method compared with the images reconstructed with the FBP method (rMBF: MRP r = 0.896 versus FBP r = 0.737, P < 0.001; rOEF: 0.915 versus 0.855, P < 0.001; rMMRO2: 0.954 versus 0.885, P < 0.001). Coefficient of variation for each parameter was significantly lower in MRP images than in FBP images (rMBF: MRP 23.5% +/- 11.3% versus FBP 30.1% +/- 14.7%, P < 0.001; rOEF: 21.0% +/- 11.1% versus 32.1% +/- 19.8%, P < 0.001; rMMRO2: 23.1% +/- 13.2% versus 30.3% +/- 19.1%, P < 0.001). CONCLUSION: The MRP reconstruction method provides higher reproducibility and lower variability in the quantitative myocardial parameters when compared with the FBP method. This study shows that the new MRP reconstruction method improves accuracy and stability of clinical quantification of myocardial blood flow and oxygen metabolism with 15O and PET.  (+info)

Taking account of between-patient variability when modeling decline in Alzheimer's disease. (8/6254)

The pattern of deterioration in patients with Alzheimer's disease is highly variable within a given population. With recent speculation that the apolipoprotein E allele may influence rate of decline and claims that certain drugs may slow the course of the disease, there is a compelling need for sound statistical methodology to address these questions. Current statistical methods for describing decline do not adequately take into account between-patient variability and possible floor and/or ceiling effects in the scale measuring decline, and they fail to allow for uncertainty in disease onset. In this paper, the authors analyze longitudinal Mini-Mental State Examination scores from two groups of Alzheimer's disease subjects from Palo Alto, California, and Minneapolis, Minnesota, in 1981-1993 and 1986-1988, respectively. A Bayesian hierarchical model is introduced as an elegant means of simultaneously overcoming all of the difficulties referred to above.  (+info)

What is Bayesian Statistics? - Definition from TechopediaWhat is Bayesian Statistics? - Definition from Techopedia
Frequentist statistics simply take the probability of a given event based on known test sets of a specific number. By contrast, Bayesian statistics take probability and allow it to express a degree of belief in an outcome, and establish reasoning based on hypotheses. Bayesian statistics was first pioneered in the 1770s by Thomas Bayes, who created the Bayes theorem that puts these ideas to work.. Another way to think about Bayesian statistics is that it utilizes conditional probabilities - it takes multiple factors into account. Think about the coin toss, where one can run large numbers of tests to determine that the frequentist statistical model is going to be close to 50 percent every time. However, Bayesian statistics might take conditional factors and apply them to that original frequentist statistic. What if one factored in whether or not it was raining when identifying the outcome of the coin toss? Might that affect the outcomes in terms of statistical results?. As a rule, ...

Bayes Theorem - The Anti-Aging Medical ClinicBayes Theorem - The Anti-Aging Medical Clinic
Bayes theorem is a probability principle set forth by the English mathematician Thomas Bayes (1702-1761). Bayes theorem is of value in medical decision-making and some of the biomedical sciences. Bayes theorem is employed in clinical epidemiology to determine the probability of a particular disease in a group of people with a specific characteristic on the basis of the overall rate of that disease and of the likelihood of that specific characteristic in healthy and diseased individuals, respectively. A common application of Bayes theorem is in clinical decision making where it is used to estimate the probability of a particular diagnosis given the appearance of specific signs, symptoms, or test outcomes. For example, the accuracy of the exercise cardiac stress test in predicting significant coronary artery disease (CAD) depends in part on the pre-test likelihood of CAD: the prior probability in Bayes theorem. In technical terms, in Bayes theorem the impact of new data on the merit of ...

MachineX: Unfolding Mystery Behind NAIVE BAYES CLASSIFIER - Knoldus BlogsMachineX: Unfolding Mystery Behind NAIVE BAYES CLASSIFIER - Knoldus Blogs
In simple terms, a Naive Bayes classifier assumes that the presence of a particular feature in a class is unrelated to the presence of any other feature. For example, a fruit may be considered to be an apple if it is red, round, and about 3 inches in diameter. Even if these features depend on each other or upon the existence of the other features, all of these properties independently contribute to the probability that this fruit is an apple and that is why it is known as Naive.. To understand the naive Bayes classifier we need to understand the Bayes theorem and to understand Bayes theorem we need to understand what is a conditional probability.. This blog will give you a brief of both conditional probabilities and Bayes theorem. Lets first quickly discuss the conditional probability and then we will move to Bayes Theorem..

Bayesian inference in phylogeny - WikipediaBayesian inference in phylogeny - Wikipedia
Bayesian inference of phylogeny uses a likelihood function to create a quantity called the posterior probability of trees using a model of evolution, based on some prior probabilities, producing the most likely phylogenetic tree for the given data. The Bayesian approach has become popular due to advances in computing speeds and the integration of Markov chain Monte Carlo (MCMC) algorithms. Bayesian inference has a number of applications in molecular phylogenetics and systematics. Bayesian inference refers to a probabilistic method developed by Reverend Thomas Bayes based on Bayes theorem. Published posthumously in 1763 it was the first expression of inverse probability and the basis of Bayesian inference. Independently, unaware of Bayes work, Pierre-Simon Laplace developed Bayes theorem in 1774. Bayesian inference was widely used until 1900s when there was a shift to frequentist inference, mainly due to computational limitations. Based on Bayes theorem, the bayesian approach combines the ...

Naive Bayes classifier - WikipediaNaive Bayes classifier - Wikipedia
Naive Bayes is a simple technique for constructing classifiers: models that assign class labels to problem instances, represented as vectors of feature values, where the class labels are drawn from some finite set. There is not a single algorithm for training such classifiers, but a family of algorithms based on a common principle: all naive Bayes classifiers assume that the value of a particular feature is independent of the value of any other feature, given the class variable. For example, a fruit may be considered to be an apple if it is red, round, and about 10 cm in diameter. A naive Bayes classifier considers each of these features to contribute independently to the probability that this fruit is an apple, regardless of any possible correlations between the color, roundness, and diameter features. For some types of probability models, naive Bayes classifiers can be trained very efficiently in a supervised learning setting. In many practical applications, parameter estimation for naive ...

A Bayesian variable selection procedure to rank overlapping gene sets | BMC Bioinformatics | Full TextA Bayesian variable selection procedure to rank overlapping gene sets | BMC Bioinformatics | Full Text
Genome-wide expression profiling using microarrays or sequence-based technologies allows us to identify genes and genetic pathways whose expression patterns influence complex traits. Different methods to prioritize gene sets, such as the genes in a given molecular pathway, have been described. In many cases, these methods test one gene set at a time, and therefore do not consider overlaps among the pathways. Here, we present a Bayesian variable selection method to prioritize gene sets that overcomes this limitation by considering all gene sets simultaneously. We applied Bayesian variable selection to differential expression to prioritize the molecular and genetic pathways involved in the responses to Escherichia coli infection in Danish Holstein cows. We used a Bayesian variable selection method to prioritize Kyoto Encyclopedia of Genes and Genomes pathways. We used our data to study how the variable selection method was affected by overlaps among the pathways. In addition, we compared our approach to

Bayesian mixture models for partially verified data - Danish National Research Database-Den Danske ForskningsdatabaseBayesian mixture models for partially verified data - Danish National Research Database-Den Danske Forskningsdatabase
Bayesian mixture models can be used to discriminate between the distributions of continuous test responses for different infection stages. These models are particularly useful in case of chronic infections with a long latent period, like Mycobacterium avium subsp. paratuberculosis (MAP) infection, where a perfect reference test does not exist. However, their discriminatory ability diminishes with increasing overlap of the distributions and with increasing number of latent infection stages to be discriminated. We provide a method that uses partially verified data, with known infection status for some individuals, in order to minimize this loss in the discriminatory power. The distribution of the continuous antibody response against MAP has been obtained for healthy, MAP-infected and MAP-infectious cows of different age groups. The overall power of the milk-ELISA to discriminate between healthy and MAP-infected cows was extremely poor but was high between healthy and MAP-infectious. The ...

Robust Medical Test Evaluation Using Flexible Bayesian Semiparametric Regression ModelsRobust Medical Test Evaluation Using Flexible Bayesian Semiparametric Regression Models
The application of Bayesian methods is increasing in modern epidemiology. Although parametric Bayesian analysis has penetrated the population health sciences, flexible nonparametric Bayesian methods have received less attention. A goal in nonparametric Bayesian analysis is to estimate unknown functions (e.g., density or distribution functions) rather than scalar parameters (e.g., means or proportions). For instance, ROC curves are obtained from the distribution functions corresponding to continuous biomarker data taken from healthy and diseased populations. Standard parametric approaches to Bayesian analysis involve distributions with a small number of parameters, where the prior specification is relatively straight forward. In the nonparametric Bayesian case, the prior is placed on an infinite dimensional space of all distributions, which requires special methods. A popular approach to nonparametric Bayesian analysis that involves Polya tree prior distributions is described. We provide example code to

N2 - This paper extends the statistical method known as generalized linear Bayesian modeling developed by Adrian Raftery to the comparison of generalized linear models across multiple groups. The extension considers all relevant hierarchical models in the model space and tests parameter equality across groups by using Bayesian posterior information from the models. The conclusion drawn by using the proposed approach tends to be more conservative than Rafterys method and the conventional likelihood ratio test, as the examples demonstrates..

Speaking of Science: Bayes Theorem and Its Relevance to Skepticism | nysec.orgSpeaking of Science: Bayes Theorem and Its Relevance to Skepticism | nysec.org
In 1763, the Reverend Thomas Bayes published An Essay towards solving a Problem in the Doctrine of Chances, containing what is now known as Bayes theorem. Bayes theorem remained relatively obscure for two centuries, but has since come to the forefront of statistical inference. Bayes simple but powerful theorem is notable for its subjectivist interpretation of probability, providing a mathematically rigorous framework for incorporating objective data into our otherwise subjective beliefs. Chris Everett will present a simple derivation of this important theorem and discuss some of its implications for everyday critical thinking and skepticism.. Chris Everett is a safety and risk analyst with thirty years experience in the areas of space systems safety, nuclear weapons safety, and missile defense lethality analysis. He currently manages the New York office of Information Systems Laboratories (ISL), where he supports NASA in the development of safety management processes and directives, the ...

Using Bayes Theorem for Command Input: Principle, Models, and Applications - Google ResearchUsing Bayes Theorem for Command Input: Principle, Models, and Applications - Google Research
Entering commands on touchscreens can be noisy, but existing interfaces commonly adopt deterministic principles for deciding targets and often result in errors. Building on prior research of using Bayes theorem to handle uncertainty in input, this paper formalized Bayes theorem as a generic guiding principle for deciding targets in command input (referred to as BayesianCommand), developed three models for estimating prior and likelihood probabilities, and carried out experiments to demonstrate the effectiveness of this formalization. More specifically, we applied BayesianCommand to improve the input accuracy of (1) point-and-click and (2) word-gesture command input. Our evaluation showed that applying BayesianCommand reduced errors compared to using deterministic principles (by over 26.9% for point-and-click and by 39.9% for word-gesture command input) or applying the principle partially (by over 28.0% and 24.5%).. ...

Applied Abstractions: Creating an activity about Bayes Theorem from a blog post
To address this I wanted to create an activity where students were to apply Bayes Theorem in a relatively simple way. Searching the internet I found the article (an essay really) An Intuitive Explanation of Bayes Theorem by Eliezer S. Yudkowsky, and thought it did a good job explaining the basic idea, and even includes different presentations of the same example. These different presentations are used to discuss innumeracy in health professionals, but provided me a variety of ways of presenting this example ...

Variational Bayes inference of spatial mixture models for segmentation. - Wellcome Centre for Integrative Neuroimaging
Mixture models are commonly used in the statistical segmentation of images. For example, they can be used for the segmentation of structural medical images into different matter types, or of statistical parametric maps into activating and nonactivating brain regions in functional imaging. Spatial mixture models have been developed to augment histogram information with spatial regularization using Markov random fields (MRFs). In previous work, an approximate model was developed to allow adaptive determination of the parameter controlling the strength of spatial regularization. Inference was performed using Markov Chain Monte Carlo (MCMC) sampling. However, this approach is prohibitively slow for large datasets. In this work, a more efficient inference approach is presented. This combines a variational Bayes approximation with a second-order Taylor expansion of the components of the posterior distribution, which would otherwise be intractable to Variational Bayes. This provides inference on fully adaptive

Naive Bayes Classifier | Brilliant Math & Science WikiNaive Bayes Classifier | Brilliant Math & Science Wiki
Naive Bayes, also known as Naive Bayes Classifiers are classifiers with the assumption that features are statistically independent of one another. Unlike many other classifiers which assume that, for a given class, there will be some correlation between features, naive Bayes explicitly models the features as conditionally independent given the class. While this may seem an overly simplistic (naive) restriction on the data, in practice naive Bayes is competitive with more sophisticated techniques and …

A Bayesian Network Model for Assessing Natural Estrogen Fate and Trans by Boknam Lee, Seth W. Kullman et al.A Bayesian Network Model for Assessing Natural Estrogen Fate and Trans by Boknam Lee, Seth W. Kullman et al.
Commercial swine waste lagoons are regarded as a major reservoir of natural estrogens, which have the potential to produce adverse physiological effects on exposed aquatic organisms and wildlife. However, there remains limited understanding of the complex mechanisms of physical, chemical, and biological processes that govern the fate and transport of natural estrogens within an anaerobic swine lagoon. To improve lagoon management and ultimately help control the offsite transport of these compounds from swine operations, a probabilistic Bayesian network model was developed to assess natural estrogen fate and budget and then compared against data collected from a commercial swine field site. In general, the model was able to describe the estrogen fate and budget in both the slurry and sludge stores within the swine lagoon. Sensitivity analysis within the model, demonstrated that the estrogen input loading from the associated barn facility was the most important factor in controlling estrogen

Bayes Factor with Lindley Paradox and Tow Standard Methods in ModelBayes Factor with Lindley Paradox and Tow Standard Methods in Model
For any statistical analysis, Model selection is necessary and required. In many cases of selection, Bayes factor is one of the important basic elements. For the unilateral hypothesis testing problem, we extend the harmony of frequency and Bayesian evidence to the generalized p-value of unilateral hypothesis testing problem, and study the harmony of generalized P-value and posterior probability of original hypothesis. For the problem of single point hypothesis testing, the posterior probability of the Bayes evidence under the traditional Bayes testing method, that is, the Bayes factor or the single point original hypothesis is established, is analyzed, a phenomenon known as the Lindley paradox, which is at odds with the classical frequency evidence of p-value. At this point, many statisticians have been worked for this from both frequentist and Bayesian perspective. In this paper, I am going to focus on Bayesian approach to model selection, starting from Bayes factors and going within Lindley Paradox,

Inflammatory disease processes involve complex and interrelated systems of mediators. Determining the causal relationships among these mediators becomes more complicated when two, concurrent inflammatory conditions occur. In those cases, the outcome may also be dependent upon the timing, severity and compartmentalization of the insults. Unfortunately, standard methods of experimentation and analysis of data sets may investigate a single scenario without uncovering many potential associations among mediators. However, Bayesian network analysis is able to model linear, nonlinear, combinatorial, and stochastic relationships among variables to explore complex inflammatory disease systems. In these studies, we modeled the development of acute lung injury from an indirect insult (sepsis induced by cecal ligation and puncture) complicated by a direct lung insult (aspiration). To replicate multiple clinical situations, the aspiration injury was delivered at different severities and at different time intervals

Bayesian probability represents a level of certainty relating to a potential outcome or idea. This is in contrast to a frequentist probability that represents the frequency with which a particular outcome will occur over any number of trials. An event with Bayesian probability of .6 (or 60%) should be interpreted as stating With confidence 60%, this event contains the true outcome, whereas a frequentist interpretation would view it as stating Over 100 trials, we should observe event X approximately 60 times. The difference is more apparent when discussing ideas. A frequentist will not assign probability to an idea, either it is true or false and it cannot be true 6 times out of 10. ...

In the situation where hypothesis H explains evidence E, Pr(E,H) basically becomes a measure of the hypothesiss explanatory power. Pr(H,E) is called the posterior probability of H. Pr(H) is the prior probability of H, and Pr(E) is the prior probability of the evidence (very roughly, a measure of how surprising it is that wed find the evidence). Prior probabilities are probabilities relative to background knowledge, e.g. Pr(E) is the likelihood that wed find evidence E relative to our background knowledge. Background knowledge is actually used throughout Bayes theorem however, so we could view the theorem this way where B is our background knowledge ...

|p|Dose-response (or ‘concentration-effect’) relationships commonly occur in biological and pharmacological systems and are well characterised by Hill curves. These curves are described by an equation with two parameters: the inhibitory concentration 50% (IC50); and the Hill coefficient. Typically just the ‘best fit’ parameter values are reported in the literature. Here we introduce a Python-based software tool, |em|PyHillFit|/em|, and describe the underlying Bayesian inference methods that it uses, to infer probability distributions for these parameters as well as the level of experimental observation noise. The tool also allows for hierarchical fitting, characterising the effect of inter-experiment variability. We demonstrate the use of the tool on a recently published dataset on multiple ion channel inhibition by multiple drug compounds. We compare the maximum likelihood, Bayesian and hierarchical Bayesian approaches. We then show how uncertainty in dose-response inputs can be

An application of Bayesian statistical methods to adaptive radiotherapy
Abstract: In adaptive radiotherapy, measured patient-specific setup variations are used to modify the patient setup and treatment plan, potentially many times during the treatment course. To estimate the setup adjustments and re-plan the treatment, the measured data are usually processed using Kalman filtering or by computing running averages. We propose, as an alternative, the use of Bayesian statistical methods, which combine a population (prior) distribution of systematic and random setup errors with the measurements to determine a patient-specific (posterior) probability distribution. The posterior distribution can either be used directly in the re-planning of the treatment or in the generation of statistics needed for adjustments. Based on the assumption that day-to-day setup variations are independent and identically distributed Normal distributions, we can efficiently compute parameters of the posterior distribution from parameters of the prior distribution and statistics of the ...

Carrier, Bayes Theorem, and Jesus Existence - The Bart Ehrman BlogCarrier, Bayes Theorem, and Jesus Existence - The Bart Ehrman Blog
As it so happens, I am finishing a PhD in the theory of probability. I may not be recognized as a world-class expert on the subject, but I may be able to contribute some useful thoughts here.. Anyway, I agree with you that the Bayesian approach cannot produce precise numerical values for the probability of historical events. So were not going to get a definite probability of Jesus existence that way. I do think, however, that the Bayesian framework can still be useful in a more qualitative way.. The basic Bayesian idea is that we have some set of mutually exclusive hypotheses H1, H2, and so on. We assign some initial (prior) probability to each of those hypotheses. We then make some observation O. There will be some conditional probability P(O,H1), which is the probability of observing O given that H1 is true. Likewise for all the other hypotheses. These conditional probabilities are called the likelihoods. Bayes theorem then allows us to move to a final probability P(H1,O), which is the ...

Fully Bayesian logistic regression with hyper-LASSO priors for high-dimensional feature selectionFully Bayesian logistic regression with hyper-LASSO priors for high-dimensional feature selection
Author(s): Li, Longhai; Yao, Weixin | Abstract: High-dimensional feature selection arises in many areas of modern science. For example, in genomic research we want to find the genes that can be used to separate tissues of different classes (e.g. cancer and normal) from tens of thousands of genes that are active (expressed) in certain tissue cells. To this end, we wish to fit regression and classification models with a large number of features (also called variables, predictors). In the past decade, penalized likelihood methods for fitting regression models based on hyper-LASSO penalization have received increasing attention in the literature. However, fully Bayesian methods that use Markov chain Monte Carlo (MCMC) are still in lack of development in the literature. In this paper we introduce an MCMC (fully Bayesian) method for learning severely multi-modal posteriors of logistic regression models based on hyper-LASSO priors (non-convex penalties). Our MCMC algorithm uses Hamiltonian Monte Carlo in a

CRAN Task View: Bayesian Inference
Applied researchers interested in Bayesian statistics are increasingly attracted to R because of the ease of which one can code algorithms to sample from posterior distributions as well as the significant number of packages contributed to the Comprehensive R Archive Network (CRAN) that provide tools for Bayesian inference. This task view catalogs these tools. In this task view, we divide those packages into four groups based on the scope and focus of the packages. We first review R packages that provide Bayesian estimation tools for a wide range of models. We then discuss packages that address specific Bayesian models or specialized methods in Bayesian statistics. This is followed by a description of packages used for post-estimation analysis. Finally, we review packages that link R to other Bayesian sampling engines such as JAGS , OpenBUGS , WinBUGS , and Stan . Bayesian packages for general model fitting ...

To calculate a Bayes factor, you need to specify your prior by providing the mean and standard deviation of the alternative. Bayes factors are quite sensitive to how you specify these priors, and for this reason, not every Bayesian statistician would recommend the use of Bayes factors. Andrew Gelman, a widely known Bayesian statistician, recently co-authored a paper in which Bayes factors were used as one of three Bayesian approaches to re-analyze data. In footnote 3 it is written: Andrew Gelman wishes to state that he hates Bayes factors - mainly because of this sensitivity to priors. So not everyone likes Bayes factors (just like not everyone likes p-values!). You can discuss the sensitivity to priors in a sensitivity analysis, which would mean plotting Bayes factors for alternative models with a range of means and standard deviations and different distributions, but I rarely see this done in practice. Equivalence tests also depend on the choice of the equivalence bounds. But it is very easy ...

This is consist with the mechanism of forward chaining which starts from searching for information about the symptoms, and then try to illustrate the conclusions. To accommodate the missing fact, expert systems can be complemented with the Bayes theorem that provides a simple rule for calculating the conditional probability so the accuracy of the method approaches the accuracy of the experts. This reseacrh uses 30 training data and 76 testing data of medical record that use hypercholesterolemia drugs from Tugurejo Hospital of Semarang.

Evaluating Different Growth Scenarios for Organic Farming Using Bayesian Techniques - AgEcon SearchEvaluating Different Growth Scenarios for Organic Farming Using Bayesian Techniques - AgEcon Search
Different views exist on the future development of organic agriculture. The Dutch government believes that in 2010 10% of the farm land will be used for organic farming. Others have a more radical view: due to increasing emphasis on sustainable production in the end all farming will be organic. Others believe in a more pessimistic scenario in which the recent growth in organic was just a temporary upswing and that the share of organic farmers already reached its maximum. In this paper different potential scenarios for the further growth of organic farming are evaluated using Bayesian techniques. A nonlinear logistic growth model explaining the share of organic farms is estimated using available historical data for Dutch agriculture. Various scenarios imply different prior values for the parameters. Because of the non-linear model specification a Metropolis-Hastings algorithm is used to simulate the posterior densities of the model parameters. Finally, using Bayesian model comparison techniques

The purpose of this study was to develop a model for predicting in-hospital trauma deaths based on this method and to compare its performance with the ICD-9-based Injury Severity Score (ICISS). Methods: The authors used Bayesian logistic regression to train and test models for predicting mortality based on injury ICD-9 codes (2,210 codes) and injury codes with two-way interactions (243,037 codes and interactions) using data from the National Trauma Data Bank (NTDB). They evaluated discrimination using area under the receiver operating curve (AUC) and calibration with the Hosmer-Lemeshow (HL) h-statistic. The authors compared performance of these

Bayesian semiparametric analysis of developmental toxicology data<...
TY - JOUR. T1 - Bayesian semiparametric analysis of developmental toxicology data. AU - Dominici, Francesca. AU - Parmigiani, Giovanni. PY - 2001. Y1 - 2001. N2 - Modeling of developmental toxicity studies often requires simple parametric analyses of the dose-response relationship between exposure and probability of a birth defect but poses challenges because of nonstandard distributions of birth defects for a fixed level of exposure. This article is motivated by two such experiments in which the distribution of the outcome variable is challenging to both the standard logistic model with binomial response and its parametric multistage elaborations. We approach our analysis using a Bayesian semiparametric model that we tailored specifically to developmental toxicology studies. It combines parametric dose-response relationships with a flexible nonparametric specification of the distribution of the response, obtained via a product of Dirichlet process mixtures approach (PDPM). Our formulation ...

Debunking Christianity: On the Christian Use of Bayes Theorem, by JP415 and GearHedEdDebunking Christianity: On the Christian Use of Bayes Theorem, by JP415 and GearHedEd
Richard Swinburne wrote a book on the resurrection using Bayes Theorem, and concluded its 97% probable that God Incarnate in the person of Jesus was raised from the dead given the existence of his god. Listen folks, this is typical delusional foolishness. Swinburne doesnt candidly say his god is his given, but thats indeed his given. Given the existence of his god he concludes its 97% probable God Incarnate in the person of Jesus was raised from the dead, because thats the only way someone can conclude God Incarnate was raised from the dead, by starting with the Christian god as a given. The specific given god cannot be a nebulous deity, or Allah or the Jewish Old Testament Yahweh, since non-Christian believers dont conclude God Incarnate arose from the dead. Even though they believe in god, they believe in a different god. [Thats why I say there is no such thing as theism, only theisms. No theist merely believes in an arbitrary set of agreed upon doctrines for discussion and ...

Title: Approximate conditional independence of separated subtrees and phylogenetic inference Abstract: Bayesian methods to reconstruct evolutionary trees from aligned DNA sequence data from different species depend on Markov chain Monte Carlo sampling of phylogenetic trees from a posterior distribution. The probabilities of tree topologies are typically estimated with the simple relative frequencies of the trees in the sample. When the posterior distribution is spread thinly over a very large number of trees, the simple relative frequencies from finite samples are often inaccurate estimates of the posterior probabilities for many trees. We present a new method for estimating the posterior distribution on the space of trees from samples based on the approximation of conditional independence between subtrees given their separation by an edge in the tree. This approximation procedure effectively spreads the estimated posterior distribution from the sampled trees to the larger set of trees that ...

This paper introduces two generative topographic mapping (GTM) methods that can be used for data visualization, regression analysis, inverse analysis, and the determination of applicability domains (ADs). In GTM-multiple linear regression (GTM-MLR), the prior probability distribution of the descriptors or explanatory variables (X) is calculated with GTM, and the posterior probability distribution of the property/activity or objective variable (y) given X is calculated with MLR; inverse analysis is then performed using the product rule and Bayes theorem. In GTM-regression (GTMR), X and y are combined and GTM is performed to obtain the joint probability distribution of X and y; this leads to the posterior probability distributions of y given X and of X given y, which are used for regression and inverse analysis, respectively. Simulations using linear and nonlinear datasets and quantitative structure-activity relationship (QSAR) and quantitative structure-property relationship (QSPR) datasets ...

The Dialogue for Reverse Engineering Assessments and Methods (DREAM) project was initiated in 2006 as a community-wide effort for the development of network inference challenges for rigorous assessment of reverse engineering methods for biological networks. We participated in the in silico network inference challenge of DREAM3 in 2008. Here we report the details of our approach and its performance on the synthetic challenge datasets. In our methodology, we first developed a model called relative change ratio (RCR), which took advantage of the heterozygous knockdown data and null-mutant knockout data provided by the challenge, in order to identify the potential regulators for the genes. With this information, a time-delayed dynamic Bayesian network (TDBN) approach was then used to infer gene regulatory networks from time series trajectory datasets. Our approach considerably reduced the searching space of TDBN; hence, it gained a much higher efficiency and accuracy. The networks predicted using our

The main goal of this thesis was to develop demographic models of the fruit fly Drosophila melanogaster using Approximate Bayesian Computation and Next Generation Sequencing Data. These models were used to reconstruct the history of African, European, and North American populations. Chapter 1 deals with the demographic history of North American D. melanogaster. This project was motivated by the release of full-genome sequences of a North American population, which showed greater diversity than European D. melanogaster although the introduction of the fruit fly to North America dates back to only �200 years ago. Here, we tested di�erent demographic models involving populations of Zimbabwe, The Netherlands, and North Carolina (North America). Among the tested models we included variants with and without migration, as well as a model involving admixture between the population of Africa and Europe that generated the population of North America. We found that the admixture model �ts best the ...

The study objective was to use Bayesian latent class analysis to evaluate the accuracy of susceptibility test results obtained from disk diffusion and broth microdilution using bacteria recovered from beef feedlot cattle. Isolates of Escherichia coli and Mannheimia haemolytica were tested for susceptibility to ampicillin, ceftiofur, streptomycin, sulfisoxazole, tetracycline, and trimethoprim-sulfamethoxazole. Results showed that neither testing method was always or even generally superior to the other. Specificity (ability to correctly classify non-resistant isolates) was extremely high for both testing methods, but sensitivity (ability to correctly classify resistant isolates) was lower, variable in the drugs evaluated, and variable between the two bacterial species. Predictive values estimated using Bayesian Markov chain Monte Carlo models showed that the ability to predict true susceptibility status was equivalent for test results obtained with the two testing methods for some drugs, but for ...

A Nonparametric Bayesian Approach to Estimating Malaria Prophylactic Effect After Two TreatmentsA Nonparametric Bayesian Approach to Estimating Malaria Prophylactic Effect After Two Treatments
Two treatment regimens for malaria are compared in their abilities to cure and combat reinfection. Bayesian analysis techniques are used to compare two typical treatment therapies for uncomplicated malaria in children under five years, not only in their power to resist recrudescence, but also how long they can postpone recrudescence or reinfection in case of failure. We present a new way of analysing this type of data using Markov Chain Monte Carlo techniques. This is done using data from clinical trials at two different centres. The results which give the full posterior distributions show that artemisinin-based combination therapy is more efficacious than sulfadoxine-pyrimethamine. It both reduced the risk of recrudescence and delayed the time until recrudescence.. ...

MPIDR - Bayesian spatial analysis of demographic survey data: an application to contraceptive use at first sexual intercourseMPIDR - Bayesian spatial analysis of demographic survey data: an application to contraceptive use at first sexual intercourse
In this paper we analyze the spatial patterns of the risk of unprotected sexual intercourse for Italian women during their initial experience with sexual intercourse. We rely on geo-referenced survey data from the Italian Fertility and Family Survey, and we use a Bayesian approach relying on weakly informative prior distributions. Our analyses are based on a logistic regression model with a multilevel structure. The spatial pattern uses an intrinsic Gaussian conditional autoregressive (CAR) error component. The complexity of such a model is best handled within a Bayesian framework, and statistical inference is carried out using Markov Chain Monte Carlo simulation. In contrast with previous analyses based on multilevel model, our approach avoids the restrictive assumption of independence between area effects. This model allows us to borrow strength from neighbors in order to obtain estimates for areas that may, on their own, have inadequate sample sizes. We show that substantial geographical ...

Inria - Bayesian Inference for Linear Dynamic Models with Dirichlet Process Mixtures
Using Kalman techniques, it is possible to perform optimal estimation in linear Gaussian state-space models. We address here the case where the noise probability density functions are of unknown functional form. A flexible Bayesian nonparametric noise model based on Dirichlet process mixtures is introduced. Efficient Markov chain Monte Carlo and Sequential Monte Carlo methods are then developed to perform optimal batch and sequential estimation in such contexts. The algorithms are applied to blind deconvolution and change point detection. Experimental results on synthetic and real data demonstrate the efficiency of this approach in various contexts.

The two approaches are evaluated for their ability to separate femoral neck fractured patients from osteoporotic controls. In total, 272 Italian women are studied. Densitometric and geometric measurements are obtained from the proximal femur by dual energy X-ray absorptiometry. The performances of the two methods are evaluated by accuracy in the classification and receiver operating characteristic curves. The Bayes classifier achieves an accuracy approximately 1% higher than that of the multiple ...

Approximate Bayesian inference in multivariate Gaussian process regression and applications to species distribution models
Gaussian processes are certainly not a new tool in the field of science. However, alongside the quick increasing of computer power during the last decades, Gaussian processes have proved to be a successful and flexible statistical tool for data analysis. Its practical interpretation as a nonparametric procedure to represent prior beliefs about the underlying data generating mechanism has gained attention among a variety of research fields ranging from ecology, inverse problems and deep learning in artificial intelligence. The core of this thesis deals with multivariate Gaussian process model as an alternative method to classical methods of regression analysis in Statistics. I develop hierarchical models, where the vector of predictor functions (in the sense of generalized linear models) is assumed to follow a multivariate Gaussian process. Statistical inference over the vector of predictor functions is approached by means of the Bayesian paradigm with analytical approximations. I developed also ...

Reference class problem - WikipediaReference class problem - Wikipedia
Applying Bayesian probability in practice involves assessing a prior probability which is then applied to a likelihood function and updated through the use of Bayes theorem. Suppose we wish to assess the probability of guilt of a defendant in a court case in which DNA (or other probabilistic) evidence is available. We first need to assess the prior probability of guilt of the defendant. We could say that the crime occurred in a city of 1,000,000 people, of whom 15% meet the requirements of being the same sex, age group and approximate description as the perpetrator. That suggests a prior probability of guilt of 1 in 150,000. We could cast the net wider and say that there is, say, a 25% chance that the perpetrator is from out of town, but still from this country, and construct a different prior estimate. We could say that the perpetrator could come from anywhere in the world, and so on. Legal theorists have discussed the reference class problem particularly with reference to the Shonubi case. ...

Dental caries are a significant public health problem. It is a disease with multifactorial causes. In Sub-Sahara Africa, Ethiopia is one of the countries with a high record of dental caries. This study was to determine the risk factors affecting dental caries using both Bayesian and classical approaches. The study design was a retrospective cohort study in the period of March 2009 to March 2013 dental caries patients Hawassa Haik Poly Higher Clinic. The Bayesian logistic regression procedure was adapted to make inference about the parameters of a logistic regression model. The purpose of this method was generating the posterior distribution of the unknown parameters given both the data and some prior density for the unknown parameters. From this study the prevalence of natural dental caries was 87% and non-natural dental caries were 13%. The age group of 18-25 was higher prevalence of dental caries than the other age groups. From Bayesian logistic regression, we found out that rural patients, do not

Burnin estimation and convergence assessment in Bayesian phylogenetic inferenceBurnin estimation and convergence assessment in Bayesian phylogenetic inference
Life is extremely complex and amazingly diverse; it has taken billions of years of evolution to attain the level of complexity we observe in nature now and ranges from single-celled prokaryotes to multi-cellular human beings. With availability of molecular sequence data, algorithms inferring homology and gene families have emerged and similarity in gene content between two genes has been the major signal utilized for homology inference. Recently there has been a significant rise in number of species with fully sequenced genome, which provides an opportunity to investigate and infer homologs with greater accuracy and in a more informed way. Phylogeny analysis explains the relationship between member genes of a gene family in a simple, graphical and plausible way using a tree representation. Bayesian phylogenetic inference is a probabilistic method used to infer gene phylogenies and posteriors of other evolutionary parameters. Markov chain Monte Carlo (MCMC) algorithm, in particular using ...

Clustering and prediction with a Gaussian process mixture model - LUTPubClustering and prediction with a Gaussian process mixture model - LUTPub
Gaussian processes provide a powerful Bayesian approach to many machine learning tasks. Unfortunately, their application has been limited by the cubic computational complexity of inference. Mixtures of Gaussian processes have been used to lower the computational costs and to enable inference on more complex data sets. In this thesis, we investigate a certain finite Gaussian process mixture model and its applicability to clustering and prediction tasks. We apply the mixture model on a multidimensional data set that contains multiple groups. We perform Bayesian inference on the model using Markov chain Monte Carlo. We find the predictive performance of the model satisfactory. Both the variances and the trends of the groups are estimated well, bar the issues caused by poor clustering. The model is unable to cluster some of the groups properly and we suggest improving the prior of the mixing proportions or incorporating more prior information as remedies for the issues in clustering ...

Image from meteorcrater.com. ... and the metal detector goes off. Well, if you said that chances are that it is from a coin a tourist dropped off, youd probably be right. But you get the gist: if the place hadnt been so thoroughly screened, it would be much more likely that a beep from the detector on a place like this came from a fragment of meteor than if we were on the streets of NYC.. What we are doing with mammography is going to a healthy population, looking for a silent disease that if not caught early can be lethal. Fortunately, the prevalence (although very high compared with other less curable cancers) is low enough that the probability of randomly encountering cancer is low, even if the results are positive, and especially in young women..

Bayes Theorem Proves Jesus Existed (And That He Didnt) : Strange NotionsBayes Theorem Proves Jesus Existed (And That He Didnt) : Strange Notions
VIII. The apostles proclaimed above all the death and resurrection of the Lord, as they bore witness to Jesus. They faithfully explained His life and words, while taking into account in their method of preaching the circumstances in which their listeners found themselves. After Jesus rose from the dead and His divinity was clearly perceived, faith, far from destroying the memory of what had transpired, rather confirmed it, because their faith rested on the things which Jesus did and taught. Nor was He changed into a mythical person and His teaching deformed in consequence of the worship which the disciples from that time on paid Jesus as the Lord and the Son of God. On the other hand, there is no reason to deny that the apostles passed on to their listeners what was really said and done by the Lord with that fuller understanding which they enjoyed, having been instructed by the glorious events of the Christ and taught by the light of the Spirit of Truth. So, just as Jesus Himself after His ...

talks.cam : Adaptive nonparametric credible ballstalks.cam : Adaptive nonparametric credible balls
If you have a question about this talk, please contact clc32.. Credible sets are central sets in the support of a posterior probability distribution, of a prescribed posterior probability. They are widely used as means of uncertainty quantification in a Bayesian analysis. We investigate the frequentist coverage of such sets in a nonparametric Bayesian setup. We show by example that credible sets can be much too narrow and misleading, and next introduce a concept of `polished tail parameters for which credible sets are of the correct order. The latter concept can be seen as a generalisation of self-similar functions as considered in a recent paper by Giné. Joint work with Botond Szabó and Harry van Zanten.. This talk is part of the Probability Theory and Statistics in High and Infinite Dimensions series.. ...
