Hi there,
I want to test for equal means and variances across twins and zygosities in a trivariate model, separately for the measures.
In the trivariate script I am using, http://ibg.colorado.edu/cdrom2014/bartels/Multivariate/Trivariate.R , the means and variances are tested together and I am not sure how to separate them.
Can I use my results from univariate saturated sub models or is there a way to test for it in a trivariate model?
Many thanks!
