Hi Alan, I've not researched this at all yet, but maybe it would be possible to fit this type of model using -gllamm- or -cmp- (both can be found easily using the -findit- command). The only other idea that I have is to look into using Mata with the appropriate matrices, which may be easier said than done.

One is a growth curve for a variable called secd which is a count variable and the other growth curve is for negative behavior, also a count. I can estimate either growth curve readilly using xtmepoisson, but I'm interested in estimating the relationship between them. That is, as secd goes up, does negative behavior go down. I would like to estimate them simultaneously as you can do with Mplus. I also have this data clustered by school. So I have 8 waves of data for each child and 15 schools. > > I could use Stata's sem to estimate parallel growth curves and see how they are related, but it is restricted to continuous variables. > > Alan Acock > acock@mac.com > A > * > * For searches and help try: > * http://www.stata.com/help.cgi?search > * http://www.stata.com/support/statalist/faq > * http://www.ats.ucla.edu/stat/stata/ * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
