Dear Dr. Muthen,

I am still learning multilevel CFA and multilevel SEM. Yet there is one thing I read from papers that confused me with what the Mplus manuals presented.

Specifically, I read about papers applying multilevel SEM, in which they reported CFI, TLI, RMSEA, and SRMR. But, in the Mplus manual sample codes and results (e.g., 9.10 or 9.8), none of these were reported.... So, is it possible to request such model fit indices through multilevel SEM or not?

Also, I saw researchers report RMSEA/SRMR while specifying it's for between or within level. Is that correct?

Thanks!

You can obtain chi-square and related fit statistics with multilevel models if you use the weighted least squares estimator. These are given for both levels.

When TYPE=RANDOM is used, only maximum likelihood estimation is available. Chi-square and related fit statistics are not available in this cases.
