st: GEE contrasts

[Sarah Mustillo <smustillo@psych.mc.duke.edu>]

Hi -

I need to produce contrasts after estimating a GEE model.  In SAS there is 
a "contrast" statement to do this.  I did a search for something similar in 
Stata and came across a contrast.ado written by the ATS people.  It is 
intended for use after ANOVAs, and it didn't work after my xtgee model.  I 
was hoping to verify that it didn't work because it isn't intended to, not 
because I did it wrong.

Anyone know if contrasts can be done after GEE models?

Thanks!

Sarah
