Factor models for ordinal variables with covariate effects on the manifest and latent variables: a comparison of LISREL and IRT approaches

By Irini Moustaki, K Joreskog and D Mavridis


We consider a general type of model for analyzing ordinal variables with covariate effects and 2 approaches for analyzing data for such models, the item response theory (IRT) approach and the PRELIS-LISREL (PLA) approach. We compare these 2 approaches on the basis of 2 examples, 1 involving only covariate effects directly on the ordinal variables and 1 involving covariate effects on the latent variables in addition
