This is an FAQ:
How can I get an R-squared value when a Stata command does not supply one?

I am comparing two xtgee models to see how much explanatory power has
increased
by adding a block of variables. I did a hausman test and the null
hypothesis
was rejected. I do want to know how much more variance was explained by the
new variables. Can the xtgee generate something like r-square type model
fit index. Or is there anyway I can come up with some formal indicators for
improvement in model fit under the new model.
