Associative Growth Mixture Model in OpenMx

Hello,

Is it currently possible to implement an Associative Growth Mixture Model in OpenMx? I was having a look at this paper from Hix-Small et al. (2004) where the authors are combining a multivariate LGM and a GMM to simultaneously
study the relationships among alcohol and marijuana use over time and investigate the existence of sub-populations.

I will probably need this approach to analyze my data, so just wondering if there is an alternative to Mplus.

Thanks

sure

I looked at Figure 1 in the article you linked. It looks feasible to estimate in OpenMx. You might start here.

some script that might help

Hi,
@MikeHunter posted this chunk of code, which along with the growth model example might help implement the Hix model in OpenMx?
