I am yet to see any response from the developers/maintainers of lme4 with respect to my posting from 25 Feburary on the R-sig-mixed-models Digest, Vol 74, Issue 40


5. Re: lmer residual variance estimate with prior weights (lmer

      wrong, lme and asreml correct) [SEC=UNCLASSIFIED] (Steve Candy)


The regression coefficients from lmer are correct but the standard errors are way too small in my example with prior (or "analytical") weights where it was not appropriate to scale the weights to sum to 1.
As previous postings note, using prior weights of sample sizes when binomial proportions are the response variable is a special case but I am not confident to use lmer with prior weights until the issue my above posting raises gets some traction.
