Evaluating model invariance in several populations: Thw example of multi-sample factor analysis for polytomous data

Abstract

The example of between-population comparison of models obtained by confirmatory factor analysis will be presented within the LISREL framework. For this purpose the Unified Parkinson?s Disease Rating scale data will be analyzed.

It will be shown
