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. 

Thanks,
Daniel Zerfu
