st: Binary & continuous endogenous vars

[Richard Williams <Richard.A.Williams.5@ND.edu>]

I think similar Qs have been asked before, but I haven't been able to 
find the answers.

X1 and X2 are exogenous and continuous.

X3 and X4 are endogenous and have reciprocal effects on each other.

X3 is a dichotomy, X4 is continuous.

For X3, I can use ivprobit, e.g.

ivprobit x3 x1 (x4 = x1 x2)

But is it legit to use ivreg for X4, e.g. do something like

ivreg x4 x2 (x3 = x1 x2)

I would assume not, but I am not sure what else I can do/ should do.
