I have tried to track down other discussions of this topic and perhaps overlooked something, but couldn't find anything that completely answers my questions.
I am using TYPE=RANDOM in order to use TSCORES for analysis of a cohort-sequential design. I would like to also use the AUXILIARY command with the '(m)' option for missing data correlates, but it appears that I cannot: "The 'm' specifier in the AUXILIARY option is not available for TYPE=RANDOM."
Is there any way to overcome this limitation, e.g., with a newer version of Mplus? Or is there some fundamental analytic limitation here?
