Hello,
I appreciate if you can help me with this problem. I have Stata/SE 8.0 and
I've been trying to estimate something using this syntax for ivreg2
ivreg2 y1 x (y2 y3 = z1 z2 z3 z4) [aweight=w] if s==1, r
or
ivreg2 y1 x (y2 y3 = z1 z2 z3 z4) [aweight=w] if s==1, liml
In any case, I get the following message
unrecognized command: mata
(error occurred while loading ivreg2.ado)
r(199);
I've re-installed the package and I still cannot make it work.
Is ivreg2 supposed to work with my Stata version?
Thanks in advance,
Benjam�n Villena
