Hi, I estimated the same model for two different groups first individually and received for both group acceptable fit values. However, when I try to estimate the model for both groups simultaniously with the "grouping" command, I receive convergence problems, although I let all loadings and correlations to load freely. How can I solve this problem? Thank you for any help.
It sounds like you have not relaxed the equality of intercepts. If all parameter equalities are relaxed, you should have twice the number of parameters as in each single group analysis. If you don't, some equalities are not relaxed.
