GMM vs. GGMM
Growth Modeling of Longitudinal Data
posted on Friday, October 27, 2006 - 2:59 pm
This is a basic question, but my limited understanding suggests that GGMM is GMM with the addition of covariates. Is that correct?
Are there examples in the User's Guide v4.1 of GGMM?
For the examples of GMM (i.e. 8.1-8.8), would these become GGMM by replacing the 'x' variable with multiple covariates?

We don't make a distinction between GMM and GGMM in the user's guide examples anymore. Adding covariates to a GMM does not make it a GGMM however. Adding a distal outcome or another growth process would.
