Re: st: GEE objects

[prathouz@uchicago.edu]

Hi Maarten --

Thanks for the response.  I did do that.  It just gives the scores for 
each individual observation, not at the cluster level.  To construct what 
I need below, it is possible to use these scores and to cycle through all 
clusters, for each cluster building the required variance-covariance 
matrix with the outputted wcorr matrix from xtgee postestimation.  This is 
the work I was trying to avoid!
