I am a new user of lme4 packages. I would appreciate if you could answer my
questions.

1. I am interested in getting the p-values for the random effect BLUPs. I
saw the discussion about the prediction intervals in the thread including
http://www.mail-archive.com/r-help@r-project.org/msg04913.html. If you can
get a prediction interval, I guess, you can also calculate a p-value. How
could you calculate the p-values?

2. How is the conditional variance, which is supplied with postVar=TRUE
option, calculated? It takes longer with postVar=TRUE and the resulting
array is just a repeat of the same matrix. It would be nicer if I could
calculate the conditional variance directly.

Thank you.
