st: 2sls with two endogenous variables(one is continuous, the other is binary)

[yi jiang <yistata@gmail.com>]

hope you guys are not too bored with endogeneity yet.
i have a linear model like Y= w q X
I believe q (continuous) and w (binary) are both endogenous. and i run
a first stage model.

i understand from some previous discussion that Wooldridge suggest a
model with one binary endogenous variable:
. probit w x1-xn z
. predict ghat
.  ivreg y x1-xn (w = ghat)

> > where:
> > y ==> outcome
> > x1-xn ==> exogenous variables
> > w ==> endogenous binary variable
> > z ==> instrument

How do i do this with two endogenous variables? any help is appreciated. thanks!
