Associative Growth Mixture Model in OpenMx
Posted on

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
