Toxicological Principles for the Safety Assessment of Food Ingredients - Chapter IV.B.4. Statistical Considerations in Toxicity Studies
Course dates: 3 weeks in July. Epidemiological research has become an important tool in the study of the aetiology and natural history of infectious and non-infectious diseases, and in assessing health effects in populations. This is a three week concentrated course on the basic principles and methods of epidemiology and medical statistics. The emphasis will be on the design and interpretation of epidemiological studies. Appropriate statistical methods will be integrated with the main epidemiological content, and practical sessions will make use of relevant computer software.. The course is relevant to clinicians and other graduates who work in medical research units, academic departments or health services. No previous formal training in epidemiology or statistics is required. Those who are confident in these methods may prefer to consider the Advanced Course in Epidemiological Analysis in September.. ...
It has been previously shown that, when both acoustic and articulatory training data are available, it is possible to improve phonetic recognition accuracy by learning acoustic features from this multi-view data with canonical correlation analysis (CCA). In contrast with previous work based on linear or kernel CCA, we use the recently proposed deep CCA, where the functional form of the feature mapping is a deep neural network. We apply the approach on a speaker-independent phonetic recognition task using data from the University of Wisconsin X-ray Microbeam Database. Using a tandem-style recognizer on this task, deep CCA features improve over earlier multi-view approaches as well as over articulatory inversion and typical neural network-based tandem features. We also present a new stochastic training approach for deep CCA, which produces both faster training and better-performing features ...

When different forms of statistical studies, and different approaches in the study of one disease, lead to a similar set of deductions, the validity of the deductions assumes a greater weight and significance. The importance of the summation of the evidence is well illustrated in the evaluation of different statistical studies of cancer of the lung and the reasonable conclusion t h a t its main cause is cigarette smoking (see Chapter IX). Another meaningful illustration of the usefulness of statistical methods may be seen in records of epidermoid cancer of the skin. In benign ulcer, there is complete destruction of muscle in the floor; and the muscularis mucosae is fused with the muscular layer at the edge of the ulcer. I n malignancy arising de novo, muscle remnants are left in the base, and there is no fusion a t the margins ; if a malignant ulcer has no muscle in its base, it may have been preceded by a peptic ulcer. 2. In benign ulcer, there is dense fibrosis underlying granulation tissue in ...

On November 12-13, 1999, an international workshop was held in Heidelberg on the relation between mobile telephones and tumors of the brain, head, and neck. Organized by the Department of Environmental Epidemiology of the German Cancer Research Center, the Institute of Medical Statistics and Documentation of the University of Mainz, and the Department of Epidemiology and Medical Statistics of the University of Bielefeld, the workshop aimed to summarize present knowledge of the health effects of mobile telephones, to report on current research activities, and to present results from a pilot-study from Germany to guide further research activities. Scientists from various European countries, the USA, and New Zealand; representatives of district and country authorities; and employees of different telephone companies participated in the workshop.. Kenneth Rothman (USA), the first speaker, summarized results from epidemiologic studies that examined the risk of cancer for amateur radio operators, ...
The output window contains additional tables, as shown in Figure 28.5. The figure displays the likelihood ratios and associated statistics for testing the hypothesis that the canonical correlations in the current row and all that follow are zero. The first approximate F value of 30.80 corresponds to the test that all canonical correlations are zero. Since the p-value is small, you can reject the null hypothesis at the 95% level. Similarly, the second approximate F value of 29.50 corresponds to the test that the second canonical correlation is zero. This test also rejects the hypothesis. Several multivariate statistics and F test approximations are also provided. These statistics test the null hypothesis that all canonical correlations are zero. The small p-values for these tests (, 0.0001) are evidence for rejecting the null hypothesis. ...
In 1950 Wyndor, with the help of his teacher Dr. Graham, collected questionnaires regarding smoking habits from hospital patients and concluded that lung cancer was associated with smoking. This belief was supported by prospective and retrospective studies by the well-known statisticians Richard Dole and Bradford Hill. As Brandt observes these new kind of studies were originated in the attempt to show that smoking caused lung cancer. Neither source discusses in any detail the reasons that the two famous statisticians Joseph Berkson in the US and R.A Fisher in the UK were not convinced that smoking caused lung cancer. Berkson explained his reasons in his article: Smoking and lung cancer: some observations on two recent reports. J Am Stat Assoc 1958;53:28-38. Here he argues that causation cannot be concluded from statistical studies which do not deal with laboratory experiments or placebo-controlled clinical trials. He is also concerned that the studies upon which causation is concluded found an ...

Downloadable! In the context of the Beckerian theory of marriage, when men and women match on a single-dimensional index that is the weighted sum of their respective multi- variate attributes, many papers in the literature have used linear canonical correlation, and related techniques, in order to estimate these weights. We argue that this estimation technique is inconsistent and suggest some solutions.

In the October Research column, I reviewed some of the background considerations for ICRs recently-concluded RATE project (Radioisotopes and the Age of The Earth). The primary hypothesis developed for the research phase of RATE was that accelerated decay could resolve the apparent conflict between the clear statements of Scripture that indicate only thousands of years since Creation and the large amount of nuclear decay in earths rocks that implies billions of years.. Details of the research and findings that support this theory may be found in the final reports of RATE: Radioisotopes and the Age of the Earth, Volume II and the book by Dr. Don DeYoung titled Thousands…Not Billions. In this column I would like to briefly discuss one portion of the RATE research project that didnt receive as much attention as I believe it deserves.. Dr. Steven Boyd of The Masters College conducted a statistical study on the historicity of Genesis 1:1-2:3 as a part of the RATE project. Since the RATE ...

Surveying the literature, the frequency distribution of single-locus heterozygosity among protein loci was examined in 95 vertebrate and 34 invertebrate species with the aim of testing the validity of the mutation-drift hypothesis. This distribution did not differ significantly from that expected under the mutation-drift hypothesis for any of the species examined when tested by the Kolmogorov-Smirnov goodness-of-fit statistic. The agreement between the observed interlocus variance of heterozygosity and its theoretical expectation was also satisfactory. There was an indication that variation in the mutation rate among loci inflates the interlocus variance of heterozygosity. The variance of heterozygosity for a homologous locus among different species was also studied. This variance generally agreed with the theoretical value very well, though in some groups of Drosophila species there was a significant discrepancy. The observed relationship between average heterozygosity and the proportion of ...
Codon degeneracy and codon usage by organisms is an interesting and challenging problem. Researchers demonstrated the relation between codon usage and various functions or properties of genes and proteins, such as gene regulation, translation rate, translation efficiency, mRNA stability, splicing, and protein domains. Researchers usually represent segments of proteins responsible for specific functions or structures in a family of proteins as sequence patterns or motifs. We asked the question if organisms use the same codons in pattern segments as compared to the rest of the sequence. We used the likelihood ratio test, Pearsons chi-squared test, and mutual information to compare these two codon usages. We showed that codon usage, in segments of genes that code for a given pattern or motif in a group of proteins, varied from the rest of the gene. The codon usage in these segments was not random. Amino acids with larger number of codons used more specific codon ratios in these segments. We studied the

Mukherjee, B., Ko, Y-A., VanderWeele, T., Roy, A., Park, S.K., Chen, J. Principal interactions analysis for repeated measures data: application to gene-gene and gene-environment interactions.. Many existing cohorts with longitudinal data on environmental exposures, occupational history, lifestyle/ behavioral characteristics, and health outcomes have collected genetic data in recent years. In this paper, we consider the problem of modeling gene-gene and gene-environment interactions with repeated measures data on a quantitative trait. We review possibilities of using classical models proposed by Tukey (1949) and Mandel (1961) using the cell means of a two-way classification array for such data. Although these models are effective for detecting interactions in the presence of main effects, they fail miserably if the interaction structure is misspecified. We explore a more robust class of interaction models that are based on a singular value decomposition of the cell-means residual matrix after ...

No one is really sure, but we think there are 400,000-500,000 piano teachers in our country, and a comparable proportion of instructors of voice and other instruments. How many of them belong to a professional organization? MTNA has about 24,000 members.. What are all the rest of those teachers doing? You may think you know, when you get a call from a transfer student who has been studying for five years and has never learned to read music. Or has been sitting on a simplified arrangement of Für Elise without progressing past the first page. In our travels, we have found that this is not the whole story. There are many fine teachers who have not yet been convinced of the benefits of association.. Recent statistical studies show us that the American public is supportive of music study. According to a poll taken by the Gallop Organization, American Attitudes Toward Music (March 2003), the overwhelming majority-from 79 percent to 98 percent of those queried, depending on the specific ...

The sensitivity of a LightCycler® 2.0 Instrument experiment depends on several factors that are common to all conventional PCRs (i.e., the quality of template, primer design, reaction conditions).. Experiments have shown that, under optimal conditions, PCR can detect a single-copy gene in 3 pg of human genomic DNA (approximately one human genome equivalent). At this concentration, statistical considerations significantly affect assay sensitivity and reproducibility. According to a Poisson distribution, the probability that a target is actually present in a given sample is approximately 67%.. Other types of DNA, such as plasmid DNA, are detectable when 1 - 10 copies are present in a sample.. ...

Most soldiers in front-line situations were being emotionally traumatized and feeling helpless at times, often greatly frightened, but it seemed that only a percentage of those soldiers were not able to handle the stress. On a related level, I also was consulting with soldiers who suffered major orthopedic injuries in warfare, often limb amputations, and I wondered about the same question, i.e., why were many of these soldiers not suffering from a Post-Traumatic Stress Disorder syndrome? In a manner of speaking, I had a built-in group of controls against which I could compare my PTSD psychiatric patients.. In almost all of the cases I examined, and this was not a statistical study, the common thread which ran through the explanations given by the orthopedic/non-PTSD patients was an attitude of resignation and release "to fate." Before combat each of these soldiers assumed the attitude that either a bullet or grenade "had their name on it" or did not. When I asked one amputee why he was not ...

Simpsons paradox is a paradox from statistics. It is named after Edward H. Simpson, a British statistician who first described it in 1951.[1] The statistician Karl Pearson described a very similar effect in 1899.[2]- Udny Yules description dates from 1903.[3] Sometimes, it is called the Yule-Simpson effect. When looking at the statistical scores of groups, these scores may change, depending on whether the groups are looked at one by one, or if they are combined into a larger group. This case often occurs in social sciences and medical statistics.[4] It may confuse people, if frequency data is used to explain a causal relationship.[5] Other names for the paradox include reversal paradox and amalgamation paradox.[6] ...

Conventional statistical significance tests do not inform the researcher regarding the likelihood that results will replicate. One strategy for evaluating result replicability is to employ a "bootstrap" re sampling of a studys data so that the stability of results across numerous configurations of the subjects can be explored. This article illustrates the use of the bootstrap in a canonical correlation analysis ...
A plot of the Kaplan-Meier estimator is a series of declining horizontal steps which, with a large enough sample size, approaches the true survival function for that population. The value of the survival function between successive distinct sampled observations ("clicks") is assumed to be constant. An important advantage of the Kaplan-Meier curve is that the method can take into account some types of censored data, particularly right-censoring, which occurs if a patient withdraws from a study, is lost to follow-up, or is alive without event occurrence at last follow-up. On the plot, small vertical tick-marks indicate individual patients whose survival times have been right-censored. When no truncation or censoring occurs, the Kaplan-Meier curve is the complement of the empirical distribution function. In medical statistics, a typical application might involve grouping patients into categories, for instance, those with Gene A profile and those with Gene B profile. In the graph, patients with Gene ...

&splt;p>Philip Sedgwick&splt;br /> Reader in medical statistics and medical education&splt;br /> Centre for Medical and Healthcare Education, St George&spamp;rsquo;s, University of London, London, UK&splt;br /> &splt;br /> Researchers investigated the suitability of a newly developed famine scale as an international definition of famine to guide humanitarian response, funding, and accountability. The scale had been proposed by Howe and Devereux, and it defined famine on the basis of intensity and magnitude. The scale was applied retrospectively to the humanitarian crisis during 2005 in Niger, West Africa, to determine whether famine had occurred. A cross sectional study design was used. Households were recruited using a stratified two stage cluster sampling method. Niger was stratified into its eight regions. Within each region, 26 villages were randomly selected, with the probability of selection proportional to the size of the village. Within each village, 20 households were systematically randomly

By default, PROC CORR prints a report that includes descriptive statistics and correlation statistics for each variable. The descriptive statistics include the number of observations with nonmissing values, the mean, the standard deviation, the minimum, and the maximum. If a nonparametric measure of association is requested, the descriptive statistics include the median. Otherwise, the sample sum is included. If a Pearson partial correlation is requested, the descriptive statistics also include the partial variance and partial standard deviation. If variable labels are available, PROC CORR labels the variables. If you specify the CSSCP, SSCP, or COV option, the appropriate sums of squares and crossproducts and covariance matrix appear at the top of the correlation report. If the data set contains missing values, PROC CORR prints additional statistics for each pair of variables. These statistics, calculated from the observations with nonmissing row and column variable values, might include the ...

As you will see from this code (because of randomized value of a/b, you might not see it the first time), values of correlation returned by the function can be higher or lower than 1.. My question: What is the statistic used for computing the correlation in this function? What range of values can it takes?. Second, additional question: Does my code is doing what I am expecting, i.e. calculating the correlation between variable a & b over scale ?. I doubt it, since the correlation value in the first bin should always be very high since my variable are perfectly correlated. However, I see differences in that first correlation values when I change the data.. ...
