Dear Linda,

I was wondering whether Mplus facilitates testing whether two tetrachoric correlation matrices are equal. If one has, for example, two groups that have binary scores on 8 items, and their tetrachoric correlation matrices seem to be different, how can I test if the cells of those matrices are significantly different across groups in Mplus? Thanks so much for your help.

This is not automated in Mplus. You would have to do it using multiple group analysis where you specify all correlations.
