Hello All,
I am working with ivqreg (ado file published by the STATA), I'd like
to insert a dummy for education (i.edu-0, 1, 2, 3) and some other
dummies.
The problem is when I run this regression, it's working in first step
and create several _cons instead of one _cons.
Is there any suggestion for treating this problem?
Thank you, Hossein
