Hi,
sorry if it is a stupid question.
I am trying a two-level CFA. It's a 1-1-1 mediation with all three slopes being random and a level-2 moderator moderating the three paths and I have missing data for all three level-1 variables.
The thing is after adding "ALGORITHM = INTEGRATION" as told by the warning, the program won't run and keeps reporting fatal error as followed
"*** FATAL ERROR
THERE IS NOT ENOUGH MEMORY SPACE TO RUN Mplus ON THE CURRENT
INPUT FILE. THE ANALYSIS REQUIRES 8 DIMENSIONS OF INTEGRATION RESULTING
IN A TOTAL OF 0.25629E+10 INTEGRATION POINTS. THIS MAY BE THE CAUSE
OF THE MEMORY SHORTAGE. YOU CAN TRY TO REDUCE THE NUMBER OF DIMENSIONS
OF INTEGRATION OR THE NUMBER OF INTEGRATION POINTS OR USE INTEGRATION=MONTECARLO
WITH FEWER NUMBER OF INTEGRATION POINTS SUCH AS 500 OR 5000."

I don't know if it is a problem of my PC or my syntax.
many thanks!

8 dimensions is very difficult to handle using ML. You can switch to Estimator = Bayes.
