Seemingly Unrelated Regression in lme4
I posted the same question a few months ago, have a look here: https://stat.ethz.ch/pipermail/r-sig-mixed-models/2012q1/018070.html and the following threads. Hope it helps, Giulia Dotti Sani, University of Trento Italy

Hello,
I am using lme4 to analyze a dataset that has crossed random effects. There
are three outcomes of interest, and currently I am using three separate
linear mixed-effects models. I would like to use seemingly unrelated
regression (SUR) to perform cross-equation tests on the fixed effects
parameters.
Is there a way to use SUR with lme4? Are there any papers that can serve as
examples or documentation that may help?
(This is my first time posting to the group, so please let me know if I
should be including other info in my post.)
