# Problem with multiple group CFA with censored variables using Mplus

I'm having problems running a multigroup CFA in Mplus for my dissertation, based on the established 4-factor model of the Hamilton Depression Scale (21 items). My dataset includes 4 left censored variables which I think may be the problem.

After the original CFA failed to output normally, I've rerun the analysis increasing the number of iterations, as advised by Mplus, but at Miterations = 2000 the output is stating;

THE LOGLIKELIHOOD DECREASED IN THE LAST EM ITERATION.  CHANGE YOUR
MODEL, STARTING VALUES AND/OR THE NUMBER OF INTEGRATION POINTS.

THE MODEL ESTIMATION DID NOT TERMINATE NORMALLY DUE TO AN ERROR IN
THE COMPUTATION.  CHANGE YOUR MODEL AND/OR STARTING VALUES.


I have no idea what I can do next, any advice would be gratefully received.
