What to do if I have a system of logit models (binary dependent variables) and wish to do SUR regression?
eg: Pr(A=1)=f(x,y), Pr(B=1)=f(x,z)

There is no such approach that I am aware of, as there is no multivariate logistic distribution.

One possible approach is alternating logistic regression:

I am not aware of a Stata implementation.
