Hi~ I am a beginner in using Mplus, recently want to try to run a CFA analysis. I am wondering what kind of data should I import in Mplus, I mean should I put correlations, covariances or just item means?
I would suggest using individual data. For continuous variables, you can also use summary data. It can be means and covariances or means, standard deviations, and correlations. See the DATA option in the Mplus User's Guide.
