structured random effects
Have you considered "lme"? For applications like this, I highly
recommend Pinheiro and Bates (2000) Mixed-Effects Models in S and S-Plus
(Springer). I failed to produce anything with "lme" until I read this
book.
hope this helps. spencer graves

Are there facilities in R or packages to estimate the parameters of a
(generalized) linear mixed model like this one: the design is crossed,
and response $y_{ij}$ relates to fixed and random effects through a
linear predictor
\[
\eta_{ij} = \beta x_{ij} + U_i - U_j
\]
where $U_1, U_2, \ldots$ are iid $N(0, \tau^2)$.
Any suggestions would be welcomed.
