STEVEN P. REISE, PH.D.: co-investigator, ucla
Steven Reise is Professor of Psychology at UCLA in Quantitative Psychology, and prior chair of that program. A graduate of the University of Minnesota, his book “Item Response Theory for Psychologists” (Embretson & Reise, 2000) is the leading textbook in item response theory (IRT) measurement, and he is winner of both the Raymond B. Cattell and Tanaka awards from the Society of Multivariate Experimental Psychology. His research interests center on the role of the bifactor model in defining and assessing dimensionality in an IRT context, outlier detection (i.e., person-fit measurement), and structural equation modeling (SEM), particularly applications of robust SEM estimation methods where outliers are down-weighted during the estimation of model parameters.
