st: Re: IVs
This is quite incorrect. When you specify
ivreg y x1 x2 (x3 x4 = x5 x6 x7)
you are saying that the FSRs are to be run with x1, x2, x5, x6, x7 as
regressors. Any other specification is quite incorrect, as has been
mentioned often on this list by Mark Schaffer, others and myself. You
cannot pick and choose which instruments enter a particular FSR.

This is a question with regards to IV's.
I am using STATA in order to do a 2SLS. STATA does not allow you to
specify which variables to include or not include in the first
stage. This means that I have to complete the regression in the
separate two stages.
