[R-sig-ME] Sample size estimation

[Chaudhari, Monica]

Hello List,

Can anybody guide me through the steps of sample size estimation for
seeing the effect (at 5% level of significance) of the difference in the
growth of outcome variable between two groups using Generalized Linear
Mixed Model with quasipoisson family. The model is as given below:

log(mu)= b0 + b1 time + b2 group + b3 time:group

Any clue will be highly appreciated.

Thanks,
Monica
