Latent variable methods
Latent variable methods are used in studies that postulate theoretical concepts involving unobservable characteristics of the participants.
Our research focuses on modelling stochastic dependence structures amongst observed and unobserved, or latent, multivariate measurements in a way that relates naturally to substantive scientific hypotheses about the underlying theoretical concepts. We are mainly concerned with studies that involve observed measurements with non-standard sampling distributions, and an underlying latent Gaussian structure.
