Spare some CPU cycles for testing lme?
If anyone has a few extra CPU cycles to spare,
I'd appreciate it if you could verify a problem that I
have encountered. Run the code
below and tell me if it crashes your R before
completion.
library(lme4)
data(bdf)
dump<-sapply( 1:50000, function(i) {
fm <- lme(langPOST ~ IQ.ver.cen + avg.IQ.ver.cen, data = bdf,
random = ~ IQ.ver.cen | schoolNR);
cat("

GLMMs & LMEs: dispersion parameters, fixed variances, design matrices
Three related questions on LMEs and GLMMs in R:
(1) Is there a way to fix the dispersion parameter (at 1) in either glmmPQL (MASS) or GLMM (lme4)?
Note: lme does not let you fix any variances in advance (presumably because it wants to "profile out" an overall sigma^2 parameter) and glmmPQL repeatedly calls lme, so I couldn't see how glmmPQL would be able to fix the dispersion
