Bernard S. Gorman, Ph.D.
SUNY Distinguished Professor, Nassau Community College
Adjunct Professor, Hofstra University

Many years ago, S.S. Stevens and others drew a distinction between categorical (nominal) scale data and ordinal, interval, and ratio scale data. While categorical data imposes fewer restrictions than other data forms, it is not an "inferior" form of data. In fact, many phenomena of interest to psychologists are naturally categorical. Unfortunately, the statistical training of most social scientists emphasizes data models and methods geared toward interval and ratio scale data. While some statistic courses give cursory coverage of contingency tables and a few nonparametric techniques, many people are unaware of the rich possibilities that other research fields have enjoyed through the use of categorical data methods. Advances in both statistical theory and software development can deliver the promises of strong categorical analyses.

The workshop will show participants how to gain the most information from two-way categorical contingency table analyses and will then provide glimpses and overviews of advanced categorical procedures such as loglinear modeling, categorical logistic regression, configural frequency analysis, correspondence analysis, categorical regression trees, and latent class analyses.

Bernard Gorman received his Ph.D. (1971) in Personality and Social Psychology from the City University of New York, and completed postdoctoral studies in psychotherapy at the Institute for Rational Emotive Therapy. He has written numerous articles and presented many convention papers in the areas of personality assessment, multivariate analysis, and relationships between cognition and affect. He co-authored the textbook, Developmental Psychology (Van Nostrand, 1980) with Theron Alexander and Paul Roodin, and co-edited the research monograph, The Personal Experience of Time (Plenum, 1977) with Alden Wessman. He is the author of several instructional computer packages published by Random House and McGraw-Hill. His book, Design and Analysis of Single Case Research, with Ronald Franklin and David Allison, focuses on the intensive study of individuals over time.

Gorman is a SUNY Distinguished Professor of Psychology and State University of New York Faculty Exchange Scholar at Nassau Community College/SUNY, where he teaches courses in general psychology, abnormal psychology, and child and adult development. He holds an adjunct professorship in Hofstra University's Graduate Psychology and Gerontology Programs, where he teaches courses in gerontology, multivariate statistical analysis, computer applications in psychology, and psychometrics. He received the State University of New York Chancellor's Award for Excellence in College Teaching. For more than 15 years, he combined his interests in measurement research, clinical issues, and teaching as a psychologist in the New York State Office of Mental Health. He served as vice-president of the Metropolitan New York Chapter of the American Statistical Association from 1993-1998. He is a Senior Research Scientist in the Department of Psychiatry at Beth Israel Medical Center, New York, where he is part of a research team investigating the efficacy of psychotherapy. He served as a member of the National Science Foundation Research Coordination Network on DNA microarray technology, where he developed multivariate statistical analysis methods for studying gene expression.

Louis H. Primavera, Ph.D.

The linear model underlies most of inferential statistics. This session will cover the basic concepts of simple linear regression and correlation including model assumptions and applications.

Dr. Primavera received his B.A. in Psychology from St. John's University and his M.A. and Ph.D. in Experimental Psychology from the City University of New York. He is currently the Dean of the Graduate School of Psychology and the Dean of the School of Health Sciences at Touro College. Dr. Primavera has published extensively and has interests in quantitative methods, drug use, and stigma and discrimination. He was a consultant to the Department of Psychiatry and Behavioral at Memorial Sloan Kettering Cancer Center for ten years and has held a number of other consulting positions in medicine, business, and education. He has been a member of a number of professional organizations and has presented at a number of annual conventions and conferences. Dr. Primavera was President of the Academic Division of the New York State Psychological Association, President of the New York City Metro Chapter of the American Statistical Association, and long time Board Member of the New York State Metro Chapter of ASA. Dr. Primavera is a Fellow of the Division of General Psychology of the American Psychological Association and a Fellow of the American Educational Research Association and a Fellow of the Eastern Psychological Association.

Kelly H. Zou, Ph.D.
Director of Statistics, Pfizer Inc., Specialty Care Business Unit
New York, New York

This presentation reviews several fundamental and important concepts concerning statistical inference, which is an extremely broad, if not all encompassing, topic. First, a historical perspective of statistical inference is provided by summarizing the developments over the last 200 years (e.g., the chi-square test constructed by Pearson and the likelihood-based statistical foundation established by Fisher). Both frequentist and Bayesian approaches are presented. Specifically, classical concepts reviewed include likelihood functions, exponential family, confidence intervals and regions, hypothesis tests, exact inference, large sample theory, and Bayesian methods. Advanced methods developed by the speaker include classification accuracy using a receiver operating characteristic analysis, monotone transformation theory, and statistical validation of predictive modeling.

This refresher course is suitable for researchers in statistics and other closely related fields. Practicing statisticians in academia, industry, and government may benefit from a review of such important and yet frequently overlooked topics. In his monograph entitled "Principles of Statistical Inference," which may serve as an important reference when reviewing these topics, Professor D.R. Cox wrote that "the object is to provide ideas and methods for the critical analysis and, as far as feasible, the interpretation of empirical data arising from a single experiment or observational study or from a collection of broadly similar studies bearing on a common target."

Key Words: Statistical Inference; Confidence Interval and Region; Maximum Likelihood Estimation; Hypothesis Tests; Transformation; Bayesian methods.

Dominick Fortugno

This presentation will introduce the mathematical processes of multiple regression, contrast this method to simple linear regression, highlight examples of multiple regression used in research today, and describe the limitations, assumptions, and best practices for using this method in psychological research. Attention will be given to specific topics such as significance testing using relative weights; incorporating power, effect size, and confidence intervals; and the use of multiple regression in test development.

Dominick A. Fortugno is a New York State certified school psychologist and Interim Director for the graduate program in school psychology at Touro College, where he teaches courses in introductory statistics, psychometric theory, and cognitive assessment. Mr. Fortugno is currently completing his doctoral dissertation in school psychology at Fordham University. His research interests include test theory and development, cognitive assessment, and the etiology and treatment of pervasive developmental disorders.
