Invariance

Invariance calculates the coefficient of congruence (Rc), a chi-square goodness of fit test, and Cattell's Salient Variable Similarity Index. The Rc can be calculated from the matching factor loadings alone. The chi-square goodness of fit method also requires that the number of subjects in each factor be entered. The salient variability similarity index requires the matching factor loadings and a user-specified value for salience.
