I have conducted a multi-sample CFA, however, the result included "THE STANDARD ERRORS OF THE MODEL PARAMETER ESTIMATES COULD NOT BE COMPUTED. THE MODEL MAY NOT BE IDENTIFIED. CHECK YOUR MODEL. PROBLEM INVOLVING PARAMETER 93." What I want to ask is about "PARAMETER 93", how can I know which is the 93rd parameter in my model?

Does using ML or MLM make the model specification different? For example, with a multi-sample CFA if I run it by ML, there are 75 free parameters, but if I run it by MLM, then there are 101 free parameters. In a multi-sample CFA, it seems the MLM by default will estimate NU and ALPHA, but I want it behave like ML, how can I do this?
Means and intercepts are included in the model with MLM. If you want the models equivalent, add TYPE=MEANSTRUCTURE to the ML analysis. Note that if there is no structure on the means or intercepts, this does not affect the rest of the model.
