Dear all,
I try to obtain the variance-covariance matrix of the estimations of
the variance covariance matrix of the random effects. I know how
obtain it using lme but I would like to obtain it with lmer(). Is it
possible?
Moreover do you know which formula is applied by ranef() to extract
the conditional modes and the conditional variance-covariance
matrix of the random effects?
Thanks in advance
Matthieu
