st: a question on xtcorr

["Bin Sun" <sun.159@osu.edu>]

Dear all,

What is the meaning of the result of xtcorr after xtgee,corr(exchangeable) for a panel data model?

Additionally, if I use xtgee,corr(ar1), does this specification mean the error term within a group is ar1? if so, is "rho" the result of xtcorr?

thanks a lot
Bin
