Hi,

I followed the guidance of Mplus manual to output some sample statistics by using SAMPSTAT option. Unlike the example showing in the manual(p.640), I just got means and correlation matrix. Meanwhile, the part of covariance matrix was not shown in the output file. However, if a correlation matrix is calculable, a covariance matrix should also exist. I am wondering whether my problem attributes to the use of ESTIMATOR=WLSMV or TYPE=COMPLEX. Any solution will be appreciated.

The sample statistics for categorical variables is a tetrachoric/polychoric correlation matrix. It sounds like this is your situation. If you need more of an explanation, please send your full output and license number to support@statmodel.com.
