You need to take into account the correlation of estimators between the two models. I think -suest- is what you need. try - help suest- tobit Y1 X1 X2 X3 X4 est store model1 tobit Y2 X1 X2 X3 est store model2 suest model1 model2 test [model1_X1 = model2_X1] On Fri, Aug 22, 2008 at 1:52 PM, olivier lohest <olohest@hotmail.com> wrote: > > Dear Statalisters, > > I have the following problem but couldnt solved it quite sometime. > > I have estimated with tobit regressions two differents equations (on cross section data) i.e > > TOBIT Y1 X1 X2 X3 X4 > > and > > TOBIT Y2 X1 X2 X3 > > the explanatory variables are the same in the two equations but the Y are not the same (Y1 is the concentration rate of firms created by a man, and Y2 is the concentration rate of firms created by a woman) > > I would like to test if the coefficients of X1 are the same in the two equations ? > > DO YOU HAVE A SOLUTION? > > HOW CAN I PROGRAM THIS IN STATA? > Thanks a lot > ol > > > > > _________________________________________________________________ > Emportez vos amis et vos emails partout… A la côte, en ville ou dans le fin fond des Ardennes ! > http://windowslivemobile.msn.com/?lang=fr-BE > * > * 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/ > -- Hau Chyi, Assistant Professor of Economics The Wang Yanan Institute for Studies in Economics (WISE) Xiamen University http://hauchyi.googlepages.com * * 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/
