I am running two-level growth model for a categorical outcome. My predictors are time-varying. Below is my codes and I got an error message saying “SINGULAR INFORMATION MATRIX PROBLEM OCCURRED IN THE UNIVARIATE ESTIMATION OF VARIABLE AMTBNG97.” This error message was for all outcome variables up to AMTBNG05. In fact, I don’t know how to fix these errors. Would you please help how to fix these errors?
Thanks a lot.
due to large size, I will add the program to the next post

I have already standardized my observed values and I have a twolevel model and I, also, aggregate the observed variables on the between level,using the command cluster_mean as you reccomend me in a previous message.
I get the same error SINGULAR INFORMATION MATRIX PROBLEM OCCURRED IN THE UNIVARIATE ESTIMATION OF VARIABLE ...
SINGULAR INFORMATION MATRIX PROBLEM OCCURRED IN THE BIVARIATE ESTIMATION OF VARIABLES ...
Can you recommend me something to fix this error???
When I run the same model without standarized my values then it takes too long to converged anf give the fatal error, that there is not enough memory.
I am not sure why you have standardized your variables. This is only correct if you have a scale free model. Please send the output before you standardized the variables and your license number to firstname.lastname@example.org.

thank you for your message, I ckecked again my data I decided not to standardized the variables. At last I refix my models and the models run.
I originally started with MLR estimator, but switched to WLSM because I couldn't obtain the GOF indicators. I have run into the same SINGULAR INFORMATION MATRIX PROBLEM problem with all my endogenous variables. I have pasted below my input. By the way, I will prefer to use the MLR estimator: do you know of any similar study that used the MLR estimator, and therefore did not report the GOF indicators.
