Subject: Questions about lme4 package
Dear there,
Thank you for reading my email. My name is Bingsong Zhang, a third year PhD student of Biostatistics at Georgetown University.
I am doing my thesis on generalized mixed model, which may rely on lme4 package. I know from the documentation that current version lme4 is not allow for specifying flexible correlation structure, so I am wondering if it possible to specify some popular structures like those available in nlmn? And how possible it is if I want to improve based on the current lme4?
Best,
Bingsong
