Rajdeep,
This was answered on Statalist not long ago:
http://www.stata.com/statalist/archive/2004-09/msg00234.html
The answer is "no, but", the "but" being that estimating the
equations separately by ivreg or ivreg2 still allows you to test the
orthogonality conditions - just not all at once.
Cheers,
Mark
