Dear Dr. Muthén With an unconditional GMM I identified five latent classes in a londitudinal dataset. These trajectories agree with theoretical expectations. Subsequently, I entered time-invariant covariates to check if these variables allow to predict growth parameter variance within these latent classes. While I found some significant predictors with this procedure, some of the resulting trajectories look quite different compared to the ones of the unconditional GMM. How do I have to interpret this? Thank you very much foryour help! |
