Hello,
I have seen that the standard way to model a GxE-moderation with OpenMx is using the "definiton variable"-approach with the moderator as a manifest definition variable. When my moderator is a latent variable it seems to me that the definition variable approach is only viable if I create the latent variable before eg. with a CFA and use it then as a "normal" variable in my data set. But I think the best way would be to integrate the measurement model into the GxE-model to assess the fit of both together. My questions is: Is it possible (a) to integrate a measurement model for the moderator in a GxE-model with OpenMx and (b) model a lantent interaction between the latent variance components and the latent moderator? I have read in the forum that it is possible to model a latent interaction with OpenMx, so actually it should not be a problem to model a latent interaction in a GxE-model or am I missing something?
