Subject: st: sample size estimates for multilevel models
Having recently switched from Windows to a Mac, I find myself missing
one thing from the Windows world -- software for sample size estimation
for multilevel models (models that one would use, e.g., -xtmixed- or
-gllamm- for).
I find that, within Stata, I can get what appears to be a reasonable
estimate by -sampsi- for repeated measures and following this with
Joanne Garrett's -sampclus- (from STB 60). However, I would like to
check the reasonableness of the answer if possible either within Stata
or with Mac software (if any).
Any suggestions are very welcome.
Thanks,
Rich
