Epidemiology and Biostatistics (EPBI) 1
Epidemiology and Biostatistics (EPBI) 1 Epidemiology and Biostatistics (EPBI) Courses EPBI 2219. Biostatistics and Public Health. 3 Credit Hours. This course is designed to provide students with a solid background in applied biostatistics in the field of public health. Specifically, the course includes an introduction to the application of biostatistics and a discussion of key statistical tests. Appropriate techniques to measure the extent of disease, the development of disease, and comparisons between groups in terms of the extent and development of disease are discussed. Techniques for summarizing data collected in samples are presented along with limited discussion of probability theory. Procedures for estimation and hypothesis testing are presented for means, for proportions, and for comparisons of means and proportions in two or more groups. Multivariable statistical methods are introduced but not covered extensively in this undergraduate course. Public Health majors, minors or students studying in the Public Health concentration must complete this course with a C or better. Level Registration Restrictions: May not be enrolled in one of the following Levels: Graduate. Repeatability: This course may not be repeated for additional credits. EPBI 2301. Public Health without Borders. 3 Credit Hours. Public Health without Borders is a course that will introduce you to the world of disease detectives to solve public health challenges in glocal (i.e., global and local) communities. You will learn about conducting disease investigations to support public health actions relevant to affected populations. You will discover what it takes to become a field epidemiologist through hands-on activities focused on promoting health and preventing disease in diverse populations across the globe. -

Good Statistical Practices for Contemporary Meta-Analysis: Examples Based on a Systematic Review on COVID-19 in Pregnancy
Review Good Statistical Practices for Contemporary Meta-Analysis: Examples Based on a Systematic Review on COVID-19 in Pregnancy Yuxi Zhao and Lifeng Lin * Department of Statistics, Florida State University, Tallahassee, FL 32306, USA; [email protected] * Correspondence: [email protected] Abstract: Systematic reviews and meta-analyses have been increasingly used to pool research find- ings from multiple studies in medical sciences. The reliability of the synthesized evidence depends highly on the methodological quality of a systematic review and meta-analysis. In recent years, several tools have been developed to guide the reporting and evidence appraisal of systematic reviews and meta-analyses, and much statistical effort has been paid to improve their methodological quality. Nevertheless, many contemporary meta-analyses continue to employ conventional statis- tical methods, which may be suboptimal compared with several alternative methods available in the evidence synthesis literature. Based on a recent systematic review on COVID-19 in pregnancy, this article provides an overview of select good practices for performing meta-analyses from sta- tistical perspectives. Specifically, we suggest meta-analysts (1) providing sufficient information of included studies, (2) providing information for reproducibility of meta-analyses, (3) using appro- priate terminologies, (4) double-checking presented results, (5) considering alternative estimators of between-study variance, (6) considering alternative confidence intervals, (7) reporting predic- Citation: Zhao, Y.; Lin, L. Good tion intervals, (8) assessing small-study effects whenever possible, and (9) considering one-stage Statistical Practices for Contemporary methods. We use worked examples to illustrate these good practices. Relevant statistical code Meta-Analysis: Examples Based on a is also provided. -

OFFICE HOURS • Instructor’s scheduled office hours: 1:15 to 2:15 Monday & Wednesday, in A441 Mayo Building • Other times are available by appointment • When really needed, can just drop in and interrupt me; could call before coming – making sure that I’m in. • I’m at a research facility on Fridays. Variables • A variable represents a characteristic or a class of measurement. It takes on different values on different subjects/persons. Examples include weight, height, race, sex, SBP, etc. The observed values, also called “observations,” form items of a data set. • Depending on the scale of measurement, we have different types of data. There are “observed variables” (Height, Weight, etc… each takes on different values on different subjects/person) and there are “calculated variables” (Sample Mean, Sample Proportion, etc… each is a “statistic” and each takes on different values on different samples). The Standard Deviation of a calculated variable is called the Standard Error of that variable/statistic. A “variable” – sample mean, sample standard deviation, etc… included – is like a “function”; when you apply it to a target element in its domain, the result is a “number”. For example, “height” is a variable and “the height of Mrs. -
Biostatistics and Experimental Design Spring 2014
Bio 206 Biostatistics and Experimental Design Spring 2014 COURSE DESCRIPTION Statistics is a science that involves collecting, organizing, summarizing, analyzing, and presenting numerical data. Scientists use statistics to discern patterns in natural systems and to predict how those systems will react in different situations. This course is designed to encourage an understanding and appreciation of the role of experimentation, hypothesis testing, and data analysis in the sciences. It will emphasize principles of experimental design, methods of data collection, exploratory data analysis, and the use of graphical and statistical tools commonly used by scientists to analyze data. The primary goals of this course are to help students understand how and why scientists use statistics, to provide students with the knowledge necessary to critically evaluate statistical claims, and to develop skills that students need to utilize statistical methods in their own studies.

Epsilon-Skew-Binormal Receiver Operating Characteristic (ROC) Curves

Roswell Park Cancer Institute, Elm & Carlton Streets, Bu®alo, NY 14263, U.S.A. Alan D. Hutson Department of Biostatistics University at Bu®alo, 249 Farber Hall, 3435 Main Street, Bu®alo, NY 14214-3000, U.S.A. April 30, 2009 Abstract In this note we extend the well-known binormal model via implementation of the epsilon-skew-normal (ESN) distribution developed by Mudholkar and Hutson (2000). We derive the equation for the receiver operating characteris- tic (ROC) curve assuming epsilon-skew-binormal (ESBN) model and examine the behavior of the maximum likelihood estimates for estimating the ESBN parameters. We then summarize the results of a simulation study to examine the asymptotic properties of the maximum likelihood estimates in the ESBN model and compare with the maximum likelihood estimates in the binormal 1 model. We also summarize the results of a simulation study comparing the two parametric models to the nonparametric ROC model. We then illustrate the maximum likelihood estimation of the ESBN model using data involving skeletal measurements in 507 physically active individuals. Keywords: AUC, diagnostic testing, prediction. 1 Introduction It is commonplace in medical studies to dichotomize a continuous predictor at a cuto® c for the purpose of diagnosing disease (yes/no). A well known method for summarizing the choice of c in terms of medical decision making is receiver operating characteristic (ROC) analysis. ROC analysis has a long history and spans parametric and non-parametric estimation methods; see [1] for some of the early references. -
