| Subject | st: Instruments over-identified |
| Date | Fri, 27 May 2011 15:19:18 +0200 (CEST) |
Dear Statalist, I need to make my model over-identified, starting with two instruments, since I want to interact my endogenous variable with some other variables. I read in previous discussions that it is possible to create new instruments by making some transformation on the available ones. Could you please indicate to me some references thus I can study how to adapt properly this tecnique to my model? Thank you in advance, Best Regards * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
