Uhm... just an idea: re-run the analysis using -xtmixed- and -post- to
work out any summaries of any particular analysis that you need as you
go?.. Or is there some functionality not present in -xtmixed- that
only HLM offers?
As for your code, check to see what exactly
mat A = (3 -5)
mat li A
produces. Not quite what you expected; you'd need to put commas
between the matrix values.
