Applied Psychometric and Sociometric Modeling

This research team is concerned with the measurement and modelling of behaviour, cognition, and unobserved traits (e.g., latent variables, missing data). Central aims include the distillation of a complex set of features into lower-dimensional representations (e.g., factor analysis, IRT), determining nonlinear relationships between traits and categorical item responses, and modelling of change over time.
