A Bayesian Perspective On Estimating Mean, Variance, And Standard-Deviation From Data, Travis E. Oliphant

Faculty Publications

This article shows how to compute confidence intervals for mean, standard-deviation, and variance using Bayesian methods. The method is implemented in SciPy as scipy.stats.bayes_mvs After reviewing some classical estimators for mean, variance, and standard-deviation and showing that un-biased estimates are not usually desirable, a Bayesian perspective is employed to determine what is known about mean, variance, and standard deviation given only that a data set in-fact has a common mean and variance. Maximum-entropy is used to argue that the likelihood function in this situation should be the same as if the data were independent and identically distributed Gaussian. A non-informative …

Correlation Versus Causality: Further Thoughts On The Law Review/Law School Liaison, Ronen Perry

Ronen Perry

This Essay is the third in a series of articles discussing the relative value of American law reviews, and a response to Professor Alfred Brophy's elaboration of my initial study of the high mathematical correlation between law review quality, as manifested in citation-based measures, and law school reputation. Given my prior interest in the relative value of American law reviews, I have used the abovementioned correlation as a means to explain some of the variance in quality among law reviews. Brophy's empirical findings overlap mine, yet the extent of his analysis, as well as his interpretation and utilization of the …

The Relative Value Of American Law Reviews: Refinement And Implementation, Ronen Perry

Ronen Perry

This Article complements a recently published paper in which I discussed the theoretical and methodological aspects of law review rankings. The purpose of this Article is twofold: refinement of the theoretical framework, and implementation. It proposes, defends, and implements a complex ranking method for general-interest student-edited law reviews, based on a judicious weighting of normalized citation frequency and normalized impact factor. It then analyzes the distribution of journals’ scores, and the diminishing marginal difference between them. Finally, it examines the correlation between law schools’ positions in the U.S. News & World Report 2006 ranking and their flagship law reviews’ positions …

A Comparison Of Microarray Analyses: A Mixed Models Approach Versus The Significance Analysis Of Microarrays, Nathan Wallace Stephens

Theses and Dissertations

DNA microarrays are a relatively new technology for assessing the expression levels of thousands of genes simultaneously. Researchers hope to find genes that are differentially expressed by hybridizing cDNA from known treatment sources with various genes spotted on the microarrays. The large number of tests involved in analyzing microarrays has raised new questions in multiple testing. Several approaches for identifying differentially expressed genes have been proposed. This paper considers two: (1) a mixed models approach, and (2) the Signiffcance Analysis of Microarrays.

The Relative Value Of American Law Reviews: A Critical Appraisal Of Ranking Methods, Ronen Perry

Ronen Perry

Ranking law reviews is not a novel initiative. Data regarding the relative value of legal periodicals was first published in 1930, in an article primarily concerned with the overall contribution of legal periodicals to the development of positive law. Since then many attempts have been made to rank American law reviews by various criteria. This Article, however, focuses not on actual rankings but on ranking theory and methodology. It offers an introductory discussion of the goals of law review rating, and the essential attributes of reliable and beneficial ranking methods, followed by a systematic and comprehensive analysis of the advantages …

Dynamic Modeling And Statistical Analysis Of Event Times, Edsel A. Pena

Faculty Publications

This review article provides an overview of recent work in the modeling and analysis of recurrent events arising in engineering, reliability, public health, biomedicine and other areas. Recurrent event modeling possesses unique facets making it different and more difficult to handle than single event settings. For instance, the impact of an increasing number of event occurrences needs to be taken into account, the effects of covariates should be considered, potential association among the interevent times within a unit cannot be ignored, and the effects of performed interventions after each event occurrence need to be factored in. A recent general class …

Patient Education In Glaucoma: What Do Patients Know About Glaucoma?, Vital Paulino Costa, George L Spaeth, Maura Smith, Cordelia Uddoh, José Paulo Cabral Vasconcellos, Newton Kara-José

Wills Eye Hospital Papers

PURPOSE: To evaluate the knowledge glaucoma patients have about their disease and its treatment.

METHODS: One hundred and eighty-three patients were interviewed at the Glaucoma Service of Wills Eye Hospital (Philadelphia, USA, Group 1) and 100 at the Glaucoma Service of University of Campinas (Campinas, Brazil, Group 2). An informal, relaxed atmosphere was created by the interviewer before asking a list of 18 open-ended questions.

RESULTS: In Group 1, 44% of the 183 patients did not have an acceptable idea about what glaucoma is, 30% did not know the purpose of the medications they were taking, 47% were not aware …

“Statistical Dueling” With Unconventional Weapons: What Courts Should Know About Experts In Employment Discrimination Class Actions, William T. Bielby, Pamela Coukos

ExpressO

When statistical evidence is offered in a litigation context, the result can be bad law and bad statistics. In recent high profile, high-stakes employment discrimination class actions against large multinationals like UPS, Wal-Mart, and Marriott, plaintiffs have claimed that decentralized and highly discretionary management practices result in systematic gender or racial disparities in pay and promotion. At class certification, plaintiffs have relied in part on statistical analyses of the company’s workforce showing companywide inequality. Defendants have responded with statistical presentations of their own, which frequently demonstrate widely varying outcomes for members of protected groups in different geographic areas of the …

A Logistic Regression Analysis Of Utah Colleges Exit Poll Response Rates Using Sas Software, Clint W. Stevenson

Theses and Dissertations

In this study I examine voter response at an interview level using a dataset of 7562 voter contacts (including responses and nonresponses) in the 2004 Utah Colleges Exit Poll. In 2004, 4908 of the 7562 voters approached responded to the exit poll for an overall response rate of 65 percent. Logistic regression is used to estimate factors that contribute to a success or failure of each interview attempt. This logistic regression model uses interviewer characteristics, voter characteristics (both respondents and nonrespondents), and exogenous factors as independent variables. Voter characteristics such as race, gender, and age are strongly associated with response. …
