Confirmatory Factor Analysis (CFA) with one measurement model. Preparation of Example 1a (input file: corger.sav) "discrimination against foreigners" with four indicators. Computation of model 1. Output interpretation. Example 1b "Factor Models with two panel waves without autocorrelation". Example 1c "Factor Model with two panel waves with autocorrelation".

Foundation of Confirmatory Factor Analysis (CFA): Assumptions, model specification and identification. Types of restrictions. Typology of model testing: parallel, tau-equivalent and congeneric models. Theoretical exercise 2. Discussion of example 1.

*Practical Session:*
