Subject | st: Testing the equality of coefficients in twoseparate probit models |
Date | Tue, 24 May 2011 14:25:12 +0200 |
Dear Stata users I am attempting to undertake a test of coefficients estimated from two probit models using xtprobit (for two different time periods). Specifically, my interest is to test the hypothesis whether some of the coefficients for two time periods are statistically different or not. Any help in how such the test can be performed in STATA is highly appreciated.
