NO CONVERGENCE. NUMBER OF ITERATIONS EXCEEDED. PROBLEM OCCURRED IN EXPLORATORY FACTOR ANALYSIS WITH 10 FACTOR(S).
The User Guide specifies that for this type of convergence problem, I should check to make sure there are no large negative variances / residual variances in the prelim parameter estimates.
So for each section of the output (EFA with 2 factors, EFA with 3 factors, etc etc) I have looked at the "estimated residual variances". I don't know what "large" would be. Can you help me understand? Is a residual variance of 0.5 large? 0.6? 0.9?
NO CONVERGENCE IN ROTATION ALGORITHM. NUMBER OF ITERATIONS EXCEEDED. PROBLEM OCCURRED IN EXPLORATORY FACTOR ANALYSIS WITH 2 FACTOR(S). THE PROBLEM IS PROBABLY DUE TO THE NEGATIVE RESIDUAL VARIANCE FOR VARIABLE F6.
However, when I switch to estimator = bayes,it is performed. Is this correct?
I ran an EFA (1 - 5) on my data and Mplus conveniently skips the output of the '3 factor model'. I've tried this on various Mplus versions and I'm still getting the same blank result. Can you please help me produce output showing all factor models?

I wanted to run an ESEM (with correlated residuals), but I didn't suceed. Following error message occurred: "NO CONVERGENCE. NUMBER OF ITERATIONS EXCEEDED. THE CHI-SQUARE STATISTIC IS NEGATIVE.THE LOGLIKELIHOOD VALUES MAY NOT BE RELIABLE." Do you have any advice what I could do?
