Timothy R. Johnson, Ph.D.
Professor, Affiliate Professor of Psychology
Broadly speaking my research interests are in psychometrics and behavioral statistics. More specific topics of interest are item response models for accounting for individual differences in response style, accounting for missing data due to coarsening or aggregation, random utility models for categorical response variables, Monte Carlo inferential methods for analytically or numerically intractable likelihood functions or posterior distributions, and quasi-parametric methods of inference and model evaluation. I also collaborate frequently with researchers in a variety of disciplines including psychology, business and economics, and natural resources and ecology.» View Timothy Johnson's Profile
