Factor Models for Ordinal Variables With Covariate Effects on the Manifest and Latent Variables: A Comparison of LISREL and IRT Approaches
Peer reviewed Peer reviewed
Direct linkDirect link
Moustaki, Irini; Joreskog, Karl G.; Mavridis, Dimitris – Structural Equation Modeling, 2004
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…

Testing for Multigroup Invariance Using AMOS Graphics: A Road Less Traveled
Peer reviewed Peer reviewed
Direct linkDirect link
Byrne, Barbara M. – Structural Equation Modeling, 2004
The purpose of this article is to illustrate the steps involved in testing for multigroup invariance using Amos Graphics. Based on analysis of covariance (ANCOV) structures, 2 applications are demonstrated, each of which represents a different set of circumstances. Application 1 focuses on the equivalence of a measuring instrument and tests for…
