I am starting to learn OpenMX and wondering if there are any scripts available for fitting growth mixture models, specified in a path-oriented notation. Any help would be greatly appreciated,
I'm sorry, but at this point, we don't have path syntax compatible with GMMs. There are several ways to specify GMMs in OpenMx, but they all involve matrices. It is a reasonable suggestion and I will bring it up at a developer meeting following our 1.0 release.
