2SLS with Probit in first stage regression

[alexcrg]

Hi,

I'd like to do a 2SLS estimation using Probit for the first-stage regression (see Wooldridge 2002 P.623).

Eg: y = a + b1x1 + b2x2 + u, where x1 is an endogenous dummy variable, and where I would like to use z1 as an instrument for x1.

So first stage regression (Probit):
x1 = a + b1z1 + b2x2 + e

Having obtained the fitted probabilities x1hat, estimate equation by IV:
y = a + b1x1hat + b2x2 + u

I'd like to know how to do this procedure on Eviews so would really appreciate advice on this.

Many thanks.
