Likelihood Functions: Functions constructed from a statistical model and a set of observed data which give the probability of that data for various values of the unknown model parameters. Those parameter values that maximize the probability are the maximum likelihood estimates of the parameters.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.Signal-To-Noise Ratio: The comparison of the quantity of meaningful data to the irrelevant or incorrect data.Algorithms: A procedure consisting of a sequence of algebraic formulas and/or logical steps to calculate or determine a given task.Computer Simulation: Computer-based representation of physical systems and phenomena such as chemical processes.Models, Statistical: Statistical formulations or analyses which, when applied to data and found to fit the data, are then used to verify the assumptions and parameters used in the analysis. Examples of statistical models are the linear model, binomial model, polynomial model, two-parameter model, etc.Markov Chains: A stochastic process such that the conditional probability distribution for a state at any future instant, given the present state, is unaffected by any additional knowledge of the past history of the system.Models, Genetic: Theoretical representations that simulate the behavior or activity of genetic processes or phenomena. They include the use of mathematical equations, computers, and other electronic equipment.Monte Carlo Method: In statistics, a technique for numerically approximating the solution of a mathematical problem by studying the distribution of some random variable, often generated by a computer. The name alludes to the randomness characteristic of the games of chance played at the gambling casinos in Monte Carlo. (From Random House Unabridged Dictionary, 2d ed, 1993)Probability: The study of chance processes or the relative frequency characterizing a chance process.Data Interpretation, Statistical: Application of statistical procedures to analyze specific observed or assumed facts from a particular study.Models, Biological: Theoretical representations that simulate the behavior or activity of biological processes or diseases. For disease models in living animals, DISEASE MODELS, ANIMAL is available. Biological models include the use of mathematical equations, computers, and other electronic equipment.

*  Association Testing in a Linked Region Using Large Pedigrees - ResearchGate
The model implemented in the computer package Mendel estimates both recombination and linkage-disequilibrium parameters and conducts likelihood-ratio tests for 1 linkage alone, 2 linkage and association simultaneously, and 3 association in the presence of linkage. In addition to the esti- mation of the recombination fraction v, separating the trait locus and the marker, we propose the estimation of the conditional frequency of the disease allele, given each marker allele. In the parametric framework of maximum-likelihood estimation, one can test null hy- potheses, such as no linkage and no association, of marker allele pi quan- q dFi 1 2 v p and q dFi p q for all i, by a likelihood-ratio test, where q is the frequency of the disease allele.

The bottom line Sep 11, 2010 At it's core, the study of mortality is based on a simple ratio - the number of deaths, D, divided by the population exposed to the risk of death, E : mortality rate = D / E While this seems simple and straightforward, there are important subtleties concerning the quality of the data used. One of these is illustrated by a series of revelations about unreported deaths in Japan, where a recent audit has cast doubt on the reliability of Japanese population statistics for the elderly. Unreported deaths reduce mortality rates both by under-counting deaths and by inflating the population at risk. Time will tell if Japan's famously low mortality rates have been under-stated as a result. . Read more Tags: mortality projections, Japan. Find by key-word. Find by date.

If you are concerned with a lack of stationarity in the data, you could try analysing the data under the LogDet substitution model with an appropriate proportion of invariable sites removed. The LogDet model is not constrained by the assumption of reversibility, so should be resistant to any shifts in the substitution process over the tree. Although it will still be susceptable to changes in the distribution of sites free to vary. Hope this helps, Thomas Jean-Fran ois Martin wrote: In butterfly mtDNA, the composition bias is extreme toward A-T 80 to 90% depending on gene and codon position.

*  Evidence under Bayes theorem
... Specifically, it compares the probability of finding particular evidence if the accused were guilty, versus if they were not guilty. An example would be the probability of finding a person's hair at the scene, if guilty, versus if just passing through the scene. Suppose, that the proposition to be proven is that defendant was the source of a hair found at the crime scene. Before learning that the hair was a genetic match for the defendant’s hair, the factfinder believes that the odds are 2 to 1 that the defendant was the source of the hair. If she used Bayes’ theorem, she could multiply those prior odds by a “likelihood ratio” in order to update her odds after learning that the hair matched the defendant’s hair. The likelihood ratio is a statistic derived by comparing the odds that the evidence expert testimony of a match would be found if the defendant was the source with the odds that it would be found if defendant was not the source. It teaches that the relevance of evidence that a proposition is true...

*  Machine Learning, etc: Naive Bayes vs. Logistic Regression
... Naive Bayes vs. Logistic Regression. There's often confusion as to the nature of the differences between Logistic Regression and Naive Bayes Classifier. One way to look at it is that Logistic Regression and NBC consider the same hypothesis space, but use different loss functions, which leads to different models for some datasets. To see that both logistic regression and naive bayes classifier consider the same hypothesis space we can rewrite Naive Bayes density as follows restricting attention to binary domain :. You can see that the conditional term is equivalent to logistic regression, so every possible conditional density that can be modelled by logistic regression can be modelled by Naive Bayes by setting \phi's aribrarily. So both logistic regression and Naive Bayes have the same hypothesis space, but optimize different objective functions. If empirical density is realizable by our model, then this coupling doesn't matter -- both conditional and marginal terms can achieve their respective maxima so ...

Title : Bayesian integration of external information into the single step approach for genomically enhanced prediction of breeding values. Author, co-author : Vandenplas, Jérémie. Event organizer : ADSA/ASAS. Keywords : Bayesian ; external information ; single step genomic procedure. However, current developments of genomic selection will bias evaluations because only records related to selected animals will be available. The single step genomic evaluation ssGBLUP could reduce pre-selection bias by the combination of genomic, pedigree and phenotypic information which are internal for the ssGBLUP. But, in opposition to multi-step methods, external information, i.e. information from outside ssGBLUP, like EBV and associated reliabilities from Multiple Across Country Evaluation which represent a priori known phenotypic informa...

*  Hyperparameter
In Bayesian statistics, a 'hyperparameter' is a parameter of a prior distribution ; the term is used to distinguish them from parameters of the model for the underlying system under analysis. For example, if one is using a beta distribution to model the distribution of the parameter 'p' of a Bernoulli distribution, then:. One may take a single value for a given hyperparameter, or one can iterate and take a probability distribution on the hyperparameter itself, called a hyperprior. One often uses a prior which comes from a parametric family of probability distributions – this is done partly for explicitness so one can write down a distribution, and choose the form by varying the hyperparameter, rather than trying to produce an arbitrary function, and partly so that one can 'vary' the hyperparameter, particularly in the method of ' conjugate prior s,' or for 'sensitivity analysis.'. When using a conjugate prior, the posterior distribution will be from the same family, but will have different hyperparameters, wh...

During the way we will develop a simple recommender engine for Firefox add-ons based on data from Telemetry and reconstruct a signal from a noisy channel. tl;dr: If you couldn’t care less about mathematical beauty and probabilities, just have a look at the recommender system. Where P D|H is the likelihood of the data D given our hypothesis H, i.e. how likely it is to see data D given that our hypothesis H is true, and P H is the prior belief about H, i.e. how likely our hypothesis H is true in the first place. According to logic, from the statement “if A is true then B is true” we can deduce that “if B is false then A is false”. So we can see that probabilistic reasoning can be applied to make logical deductions, i.e. Recommender Engine. Telemetry submissions contain the IDs of the add-ons of our users.

Abstract Longitudinal data can be used to estimate the transition intensities between healthy and unhealthy states prior to death. An illness-death model for history of stroke is presented, where time-dependent transition intensities are regressed on a latent variable representing cognitive function. The change of this function over time is described by a linear growth model with random effects.

WHAT IS BAYESIAN/FREQUENTIST INFERENCE. Nate Silver’s book, various comments on my blog, comments on other blogs, Sharon McGrayne’s book, etc have made it clear to me that there is still a lot of confusion about what Bayesian inference is and what Frequentist inference is. Frequentist inference and Bayesian Inference are defined by their goals, not their methods. Saying That Confidence Intervals Do Not Represent Degrees of Belief Is Not a Criticism of Frequentist Inference. Saying That Posterior Intervals Do Not Have Frequency Coverage Properties Is Not a Criticism of Bayesian Inference. And conversely, it is possible to do Bayesian inference without using Bayes’ theorem as Michael Goldstein, for example, has shown. As I will discuss in that review, Nate argues forcefully that Bayesian analysis is superior to Frequentist anal...

'Bayesian approaches to brain function' investigate the capacity of the nervous system to operate in situations of uncertainty in a fashion that is close to the optimal prescribed by Bayesian statistics.

All Downloads Events Groups News People Projects Publications Videos. Structure Learning with Nonparametric Decomposable Models Anton Schwaighofer, Mathäus Dejori, Volker Tresp, and Martin Stetter 2007. Abstract We present a novel approach to structure learning for graphical models. By using nonparametric estimates to model clique densities in decomposable models, both discrete and continuous distributions can be handled in a unified framework. Also, consistency of the underlying probabilistic model is guaranteed. Model selection is based on predictive assessment, with efficient algorithms that allow fast greedy forward and backward selection within the class of decomposable models. We show the validity of this structure learning approach on toy data, and on two large sets of gene expression data. Details Publication type Inproceedings. Published in Artificial N...

*  .. Debunking Two Nate Silver Myths
There is nothing big data about Nate's methods. That's big data. That is big data. The fact is, he didn't need big data to do this. Look at it this way, if a meteorologist says there a 90% chance of rain where you live and it doesn't rain, the forecast wasn't necessarily wrong, because 10% of the time it shouldn't rain - otherwise the odds would be something other than a 90% chance of rain. In a frequentist interpretation, saying that an outcome of an event has a probability X% of occuring, you're saying that if you were to run an infinite series of repetitions of the event, then on average, the outcome would occur in X out of every 100 events. What it says is: for any specific event, it will have one outcome. But given the current state of information available to me , I can have a certain amount of certainty about whether or not the event will occur. It just means that given the current state of my knowledge, I expect a particular outcome, and the information I know gives me that degree of certainty. Bayesi...

*  .. Dr. Bayes, or How I Learned to Stop Worrying and Love Updating .. Author .. Follow me on Twitte
Updating is really just a form of learning, but Bayes’ theorem gives us a way to structure that learning that turns out to be very powerful. A big part of my professional life involves using statistical models to forecast rare political events, and I am deeply frustrated by frequent encounters with people who dismiss statistical forecasts out of hand see here and here for previous posts on the subject . It’s probably unrealistic of me to think so, but I am hopeful that recognition of the intuitive nature and power of Bayesian updating might make it easier for skeptics to make use of my statistical forecasts and others like them. I’m a firm believer in the forecasting power of statistical models, so I usually treat a statistical forecast as my initial belief or prior, in Bayesian jargon and then only revise that forecast as new information arrives. When the statistical forecast diverges from your prior belief, Bayes’ theorem offers a structured but simple way to arrive at a new estimate. Experience shows tha...

*  Computer experiment
Background Objectives Computer simulation modeling Gaussian process prior. Design of computer experiments Problems with massive sample sizes. 'Bias correction': Use physical data to correct for bias in the simulation. Computer simulation modeling. Modeling of computer experiments typically uses a Bayesian framework. The basic idea of this framework is to model the computer simulation as an unknown function of a set of inputs. It is natural to see the simulation as a deterministic function that maps these 'inputs' into a collection of 'outputs'. For some simulations, such as climate models, evaluation of the output for a single set of inputs can require millions of computer hours. Gaussian process prior. The typical model for a computer code output is a Gaussian process. Owing to the Bayesian framework, we fix our belief that the function f follows a Gaussian process, f \sim \operatorname{GP} m \cdot,C \cdot,\cdot, where m is the mean function and C is the covariance function. Popular mean functions are low or...

Other Article Types. Article-Level Metrics. Article. New York data were used to estimate numerators for ICU and death, and two sources of data—medically attended cases in Milwaukee or self-reported influenza-like illness ILI in New York—were used to estimate ratios of symptomatic cases to hospitalizations. Using medically attended cases and estimates of the proportion of symptomatic cases medically attended, we estimated an sCFR of 0.048% 95% credible interval 0.026%–0.096%, sCIR of 0.239% 0.134%–0.458%, and sCHR of 1.44% 0.83%–2.64%. By using data on medically attended and hospitalized cases of pH1N1 infection in Milwaukee and information from New York City on hospitalizations, intensive care use, and deaths, the researchers estimate that the proportion of US cases with symptoms that died the sCFR during summer 2009 was 0.048%.

I've read about the master theorem for solving recurrences in Introduction to Algorithms, but have a problem probably, due to misunderstanding while applying it in some cases. For example, having recurrence $T n = 5 T \frac{n}{3} + \Theta n 2 \log n $ and trying to apply this theorem I have: $a=5; b=3; f n =\Theta n 2 \log n $. But as I understand, $f n = \Theta n 2 \log n $ doesn't imply regularity of $f n $ and the master theorem is impossible to apply in this case. It would help if you told us what the master theorem says. Marek Feb 13 '13 at 14:07. Marek Feb 13 '13 at 14:31.

Abstract We appeal to the theory of Bayesian Networks to model different strategies for obtaining confirmation for a hypothesis from experimental test results provided by less than fully reliable instruments. In particular, we consider i repeated measurements of a single testable consequence of the hypothesis, ii measurements of multiple testable consequences of the hypothesis, iii theoretical support for the reliability of the instrument, and iv calibration procedures. We evaluate these strategies on their relative merits under idealized conditions and s...

... 'Cross-species transmission CST ' is the phenomenon of transfer of viral infection from one species, usually a similar species, to another. Often seen in emerging viruses where one species transfers to another which in turn transfers to humans. Examples include HIV-AIDS, SARS, Ebola, Swine flu, rabies, and Bird flu. Faria NR, Suchard MA, Rambaut A, Streicker DG, Lemey P. Simultaneously reconstructing viral cross-species transmission history and identifying the underlying constraints. Philos Trans R Soc Lond B Biol Sci. 2013 Feb 4;368 1614. The exact mechanism that facilitates the transfer is unknown, however, it is believed that viruses with a rapid mutation rate are able to overcome host-specific immunological defenses. This can occur between species that have high contact rates. It can also occur between species with low contact rates but usually through an intermediary species.

*  Bayesian Operational Modal Analysis
... 'Bayesian Operational Modal Analysis' BAYOMA adopts a Bayesian system identification approach for Operational Modal Analysis OMA. Operational Modal Analysis OMA aims at identifying the modal properties natural frequencies, damping ratio s, mode shape s, etc. The input excitations to the structure are not measured but are assumed to be ' ambient ' 'broadband random'. In a Bayesian context, the set of modal parameters are viewed as uncertain parameters or random variables whose probability distribution is updated from the prior distribution before data to the posterior distribution after data. The peak s of the posterior distribution represents the most probable value s 'MPV' suggested by the data, while the spread of the distribution around the MPV reflects the remaining uncertainty of the parameters. Pros and Cons Methods Notes See also References. In the absence of input loading information, the identified modal properties from OMA often have significantly larger uncertainty or variability than their co...

*  Deviance (statistics)
In statistics, 'deviance' is a quality of fit statistic for a model that is often used for statistical hypothesis testing. It is a generalization of the idea of using the sum of squares of residuals in ordinary least squares to cases where model-fitting is achieved by maximum likelihood. Definition See also Notes References External links. The deviance for a model 'M' 0, based on a dataset 'y', is defined as:. : D y = -2 \Big \log \big p y\mid\hat \theta 0 \big -\log \big p y\mid\hat \theta s \big \Big .\,. Here \hat \theta 0 denotes the fitted values of the parameters in the model 'M' 0, while \hat \theta s denotes the fitted parameters for the "full model" or "saturated model" : both sets of fitted values are implicitly functions of the observations 'y'. Here the 'full model' is a model with a parameter for every observation so that the data are fitted exactly. In particular, suppose that 'M 1 ' contains the parameters in 'M 2 ', and 'k' additional parameters. Then, under the null hypothesis that 'M 2 ' is ...

Bayesian Calibration of Computer Model Ensembles Pratola, M Los Alamos National Laboratory Friday 09 September 2011, 11:30-12:00 Seminar Room 1, Newton Institute. Abstract Using field observations to calibrate complex mathematical models of a physical process allows one to obtain statistical estimates of model parameters and construct predictions of the observed process that ideally incorporate all sources of uncertainty. Many of the methods in the literature use response surface approaches, and have demonstrated success in many applications. However there are notable limitations, such as when one has a small ensemble of model runs where the model outputs are high dimensional. In such instances, arriving at a response surface model that reasonably describes the process can be dicult, and computational issues may also render the approach impractical. In this talk we present an approach that has numerous beneifts compared to some popular m...

*  Bayesian vector autoregression
... in statistics bayesian vector autoregression bvar uses bayesian methods to estimate a vector autoregression var in that respect the difference with standard var models lies in the fact that the model parameters are treated as random variable s and prior probabilities are assigned to them vector autoregressions are flexible statistical models that typically include many free parameters given the limited length of standard macroeconomic datasets bayesian methods have become an increasingly popular way of dealing with this problem of over parameterization the general idea is to use informative priors to shrink the unrestricted model towards a parsimonious naïve benchmark thereby reducing parameter uncertainty and improving forecast accuracy see for a survey a typical example is the shrinkage prior proposed by robert litterman and subsequently developed by other researchers at university of minnesota which is known in the bvar literature as the minnesota prior the informativeness of the prior can be set by t...

Decoding methods: In coding theory, decoding is the process of translating received messages into codewords of a given code. There have been many common methods of mapping messages to codewords.Hyperparameter: In Bayesian statistics, a hyperparameter is a parameter of a prior distribution; the term is used to distinguish them from parameters of the model for the underlying system under analysis.Clonal Selection Algorithm: In artificial immune systems, Clonal selection algorithms are a class of algorithms inspired by the clonal selection theory of acquired immunity that explains how B and T lymphocytes improve their response to antigens over time called affinity maturation. These algorithms focus on the Darwinian attributes of the theory where selection is inspired by the affinity of antigen-antibody interactions, reproduction is inspired by cell division, and variation is inspired by somatic hypermutation.Interval boundary element method: Interval boundary element method is classical boundary element method with the interval parameters.
Inverse probability weighting: Inverse probability weighting is a statistical technique for calculating statistics standardized to a population different from that in which the data was collected. Study designs with a disparate sampling population and population of target inference (target population) are common in application.Vladimir Andreevich Markov: Vladimir Andreevich Markov (; May 8, 1871 – January 18, 1897) was a Russian mathematician, known for proving the Markov brothers' inequality with his older brother Andrey Markov. He died of tuberculosis at the age of 25.Monte Carlo methods for option pricing: In mathematical finance, a Monte Carlo option model uses Monte Carlo methods Although the term 'Monte Carlo method' was coined by Stanislaw Ulam in the 1940s, some trace such methods to the 18th century French naturalist Buffon, and a question he asked about the results of dropping a needle randomly on a striped floor or table. See Buffon's needle.Negative probability: The probability of the outcome of an experiment is never negative, but quasiprobability distributions can be defined that allow a negative probability for some events. These distributions may apply to unobservable events or conditional probabilities.Matrix model: == Mathematics and physics ==

(1/5116) An evaluation of elongation factor 1 alpha as a phylogenetic marker for eukaryotes.

Elongation factor 1 alpha (EF-1 alpha) is a highly conserved ubiquitous protein involved in translation that has been suggested to have desirable properties for phylogenetic inference. To examine the utility of EF-1 alpha as a phylogenetic marker for eukaryotes, we studied three properties of EF-1 alpha trees: congruency with other phyogenetic markers, the impact of species sampling, and the degree of substitutional saturation occurring between taxa. Our analyses indicate that the EF-1 alpha tree is congruent with some other molecular phylogenies in identifying both the deepest branches and some recent relationships in the eukaryotic line of descent. However, the topology of the intermediate portion of the EF-1 alpha tree, occupied by most of the protist lineages, differs for different phylogenetic methods, and bootstrap values for branches are low. Most problematic in this region is the failure of all phylogenetic methods to resolve the monophyly of two higher-order protistan taxa, the Ciliophora and the Alveolata. JACKMONO analyses indicated that the impact of species sampling on bootstrap support for most internal nodes of the eukaryotic EF-1 alpha tree is extreme. Furthermore, a comparison of observed versus inferred numbers of substitutions indicates that multiple overlapping substitutions have occurred, especially on the branch separating the Eukaryota from the Archaebacteria, suggesting that the rooting of the eukaryotic tree on the diplomonad lineage should be treated with caution. Overall, these results suggest that the phylogenies obtained from EF-1 alpha are congruent with other molecular phylogenies in recovering the monophyly of groups such as the Metazoa, Fungi, Magnoliophyta, and Euglenozoa. However, the interrelationships between these and other protist lineages are not well resolved. This lack of resolution may result from the combined effects of poor taxonomic sampling, relatively few informative positions, large numbers of overlapping substitutions that obscure phylogenetic signal, and lineage-specific rate increases in the EF-1 alpha data set. It is also consistent with the nearly simultaneous diversification of major eukaryotic lineages implied by the "big-bang" hypothesis of eukaryote evolution.  (+info)

(2/5116) Unusually high evolutionary rate of the elongation factor 1 alpha genes from the Ciliophora and its impact on the phylogeny of eukaryotes.

The elongation factor 1 alpha (EF-1 alpha) has become widely employed as a phylogenetic marker for studying eukaryotic evolution. However, a disturbing problem, the artifactual polyphyly of ciliates, is always observed. It has been suggested that the addition of new sequences will help to circumvent this problem. Thus, we have determined 15 new ciliate EF-1 alpha sequences, providing for a more comprehensive taxonomic sampling of this phylum. These sequences have been analyzed together with a representation of eukaryotic sequences using distance-, parsimony-, and likelihood-based phylogenetic methods. Such analyses again failed to recover the monophyly of Ciliophora. A study of the substitution rate showed that ciliate EF-1 alpha genes exhibit a high evolutionary rate, produced in part by an increased number of variable positions. This acceleration could be related to alterations of the accessory functions acquired by this protein, likely to those involving interactions with the cytoskeleton, which is very modified in the Ciliophora. The high evolutionary rate of these sequences leads to an artificial basal emergence of some ciliates in the eukaryotic tree by effecting a long-branch attraction artifact that produces an asymmetric topology for the basal region of the tree. The use of a maximum-likelihood phylogenetic method (which is less sensitive to long-branch attraction) and the addition of sequences to break long branches allow retrieval of more symmetric topologies, which suggests that the asymmetric part of the tree is most likely artifactual. Therefore, the sole reliable part of the tree appears to correspond to the apical symmetric region. These kinds of observations suggest that the general eukaryotic evolution might have consisted of a massive radiation followed by an increase in the evolutionary rates of certain groups that emerge artificially as early branches in the asymmetric base of the tree. Ciliates in the case of the EF-1 alpha genes would offer clear evidence for this hypothesis.  (+info)

(3/5116) Interaction of process partitions in phylogenetic analysis: an example from the swallowtail butterfly genus Papilio.

In this study, we explored how the concept of the process partition may be applied to phylogenetic analysis. Sequence data were gathered from 23 species and subspecies of the swallowtail butterfly genus Papilio, as well as from two outgroup species from the genera Eurytides and Pachliopta. Sequence data consisted of 1,010 bp of the nuclear protein-coding gene elongation factor-1 alpha (EF-1 alpha) as well as the entire sequences (a total of 2,211 bp) of the mitochondrial protein-coding genes cytochrome oxidase I and cytochrome oxidase II (COI and COII). In order to examine the interaction between the nuclear and mitochondrial partitions in a combined analysis, we used a method of visualizing branch support as a function of partition weight ratios. We demonstrated how this method may be used to diagnose error at different levels of a tree in a combined maximum-parsimony analysis. Further, we assessed patterns of evolution within and between subsets of the data by implementing a multipartition maximum-likelihood model to estimate evolutionary parameters for various putative process partitions. COI third positions have an estimated average substitution rate more than 15 times that of EF-1 alpha, while COII third positions have an estimated average substitution rate more than 22 times that of EF-1 alpha. Ultimately, we found that although the mitochondrial and nuclear data were not significantly incongruent, homoplasy in the fast-evolving mitochondrial data confounded the resolution of basal relationships in the combined unweighted parsimony analysis despite the fact that there was relatively strong support for the relationships in the nuclear data. We conclude that there may be shortcomings to the methods of "total evidence" and "conditional combination" because they may fail to detect or accommodate the type of confounding bias we found in our data.  (+info)

(4/5116) Diagnosing anaemia in pregnancy in rural clinics: assessing the potential of the Haemoglobin Colour Scale.

Anaemia in pregnancy is a common and severe problem in many developing countries. Because of lack of resources and staff motivation, screening for anaemia is often solely by clinical examination of the conjunctiva or is not carried out at all. A new colour scale for the estimation of haemoglobin concentration has been developed by WHO. The present study compares the results obtained using the new colour scale on 729 women visiting rural antenatal clinics in Malawi with those obtained by HemoCue haemoglobinometer and electronic Coulter Counter and with the assessment of anaemia by clinical examination of the conjunctiva. Sensitivity using the colour scale was consistently better than for conjunctival inspection alone and interobserver agreement and agreement with Coulter Counter measurements was good. The Haemoglobin Colour Scale is simple to use, well accepted, cheap and gives immediate results. It shows considerable potential for use in screening for anaemia in antenatal clinics in settings where resources are limited.  (+info)

(5/5116) Laboratory assay reproducibility of serum estrogens in umbilical cord blood samples.

We evaluated the reproducibility of laboratory assays for umbilical cord blood estrogen levels and its implications on sample size estimation. Specifically, we examined correlation between duplicate measurements of the same blood samples and estimated the relative contribution of variability due to study subject and assay batch to the overall variation in measured hormone levels. Cord blood was collected from a total of 25 female babies (15 Caucasian and 10 Chinese-American) from full-term deliveries at two study sites between March and December 1997. Two serum aliquots per blood sample were assayed, either at the same time or 4 months apart, for estrone, total estradiol, weakly bound estradiol, and sex hormone-binding globulin (SHBG). Correlation coefficients (Pearson's r) between duplicate measurements were calculated. We also estimated the components of variance for each hormone or protein associated with variation among subjects and variation between assay batches. Pearson's correlation coefficients were >0.90 for all of the compounds except for total estradiol when all of the subjects were included. The intraclass correlation coefficient, defined as a proportion of the total variance due to between-subject variation, for estrone, total estradiol, weakly bound estradiol, and SHBG were 92, 80, 85, and 97%, respectively. The magnitude of measurement error found in this study would increase the sample size required for detecting a difference between two populations for total estradiol and SHBG by 25 and 3%, respectively.  (+info)

(6/5116) Maximum-likelihood generalized heritability estimate for blood pressure in Nigerian families.

Elevated blood pressure (BP) is more common in relatives of hypertensives than in relatives of normotensives, indicating familial resemblance of the BP phenotypes. Most published studies have been conducted in westernized societies. To assess the ability to generalize these estimates, we examined familial patterns of BP in a population-based sample of 510 nuclear families, including 1552 individuals (320 fathers, 370 mothers, 475 sons, and 387 daughters) from Ibadan, Nigeria. The prevalence of obesity in this community is low (body mass index: fathers, 21.6; mothers, 23.6; sons, 19.2; and daughters=21.0 kg/m2). The BP phenotype used in all analyses was created from the best regression model by standardizing the age-adjusted systolic blood pressure (SBP) and diastolic blood pressure (DBP) to 0 mean and unit variance. Heritability was estimated by use of the computer program SEGPATH from the most parsimonious model of "no spouse and neither gender nor generation difference" as 45% for SBP and 43% for DBP. The lack of a significant spouse correlation is consistent with little or no influence of the common familial environment. However, the heritability estimate of <50% for both SBP and DBPs reinforces the importance of the nonshared environmental effect.  (+info)

(7/5116) A gene for X-linked idiopathic congenital nystagmus (NYS1) maps to chromosome Xp11.4-p11.3.

Congenital nystagmus (CN) is a common oculomotor disorder (frequency of 1/1,500 live births) characterized by bilateral uncontrollable ocular oscillations, with onset typically at birth or within the first few months of life. This condition is regarded as idiopathic, after exclusion of nervous and ocular diseases. X-linked, autosomal dominant, and autosomal recessive modes of inheritance have been reported, but X-linked inheritance is probably the most common. In this article, we report the mapping of a gene for X-linked dominant CN (NYS1) to the short arm of chromosome X, by showing close linkage of NYS1 to polymorphic markers on chromosome Xp11.4-p11.3 (maximum LOD score of 3.20, over locus DXS993). Because no candidate gene, by virtue of its function, has been found in this region of chromosome Xp, further studies are required, to reduce the genetic interval encompassing the NYS1 gene. It is hoped that the complete gene characterization will address the complex pathophysiology of CN.  (+info)

(8/5116) A note on power approximations for the transmission/disequilibrium test.

The transmission/disequilibrium test (TDT) is a popular method for detection of the genetic basis of a disease. Investigators planning such studies require computation of sample size and power, allowing for a general genetic model. Here, a rigorous method is presented for obtaining the power approximations of the TDT for samples consisting of families with either a single affected child or affected sib pairs. Power calculations based on simulation show that these approximations are quite precise. By this method, it is also shown that a previously published power approximation of the TDT is erroneous.  (+info)
