Hello R users,
I've read the posts on this topic, and had a look at the R documentation for
nlme, but I can't seem to make this work. I'd like to be able to fit a mixed
effects model with crossed random effects, but also be able to specify the
covariance matrix structure for the residuals.
Hi Ben,
Pinheiro and Bates 2000 is the real documentation for nlme. See the
Cell Culture Bioassay example starting on pg 163 for a demonstration
of fitting crossed random effects using pdIdent and pdBlocked objects.
hth,
Kingsford
