Analyzing multigroup data with structural equation models
Görz, Nicole; Hildebrandt, Lutz; Annacker, Dirk - 2000
In empirical applications of structural equation modeling researchers often assume that the sample under investigation is homogenous unless observed characteristics allow for a division of the sample into mutual exclusive homogenous subgroups. If such information is not available, unobserved...

Structural equation models for finite mixtures : simulation results and empirical applications
Temme, Dirk; Williams, John R.; Hildebrandt, Lutz - 2002
Unobserved heterogeneity is a serious but often neglected problem in structural equation modelling (SEM) challenging the validity of many empirical results. Recently, a finite mixture approach to SEM has been proposed to resolve this problem but until now only a few studies analyse the...
