lmer and correlation
Hello list,
I've been reading through the archives and it seems as though, as
of right now, there is no way to specify the correlation structure in
lmer. I was wondering if anyone knows if this is going to be
implemented? I'm using mixed-effects models within a tree structure,
so I make a lot of calls to lme to get the resulting deviance, and
lmer2 is almost 5 times faster than lme
