st: (sorry, wrong listser) Question about GEE error term

["Bryan W. Griffin" <bwgriffin@georgiasouthern.edu>]

Sorry folks, I erroneously posted the message below to Stata listserv and 
intended to send to Multilevel listserv instead. The query below does not 
include a Stata specific question.  (If anyone happens to have a response 
anyway, please send it to me directly and not to the list -- thanks!)
