Dear Statalist,
I was wondering if anyone knows how I could obtain the standard error for the covariance between interaction effect and the group variable in mixed effect model for each individual prediction. Here are more details:
I ran a mixed effect model mixed weight week||id:week,cov(unstructured)
and i was able to obtain the standard errors for each prediction using
predict m*, reffects reses(s*)
However, I looked around and wasn't able to find a way to obtain the standard error for covariance (note that I have the covariance unstructured). would appreciate any help! Thanks for your time in advance.
