Dear Statalist: I am estimating two differently-specified IV regressions and trying to compare coefficients between the two models. I tried: ivregress 2sls y x1 x2 (x1=z) est store reg1 ivregress 2sls y x1 x2 x3 (x1=z) est store reg2 test [reg1]_b[x1]=[reg2]_b[x1] Then I get "equation [reg1] not found" error. What am I doing wrong? Thanks. * * 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/
