Hi ,

I use library(gee),library(geepack),library(yags) perform GEE data analysis
, but all of them cannot do variable selection!

Both step and stepAIC can do variable selection based on AIC criterion under
linear regression and glm,
  but they  cannot work when model is based on GEE.

I want to ask whether any variable selection function or package under GEE
model avaliable now?
Thanks!

Best,
