Sounds like a problem for -treatreg- in the cross-sectional context, but I
cannot think of a similar -xt- command straight away...

Hi,

Can XTIVREG be used in the case of discrete endogenous variables in some
way?

I have a problem such as:

Y  = f(a,b,c)
a = f(z,b,c)

where 'a' is a dichotomy. For 'z' to be an instrument for 'a' then
there is a co-linearity problem.

Thanks
Jeff
