Dear all,
I had estimated the regression coefficients for a panel (using xtgee). This was 8 months ago. I use this model to analyze the behavior of taxpayers and asses certain features. Now, I have updated the panel; i.e. I have fitted a new xtgee model with this panel. However, the coefficients look similar to the ones I'd estimated before.
What test (or tests) should I perform in order to proving this hypothesis (H0: coeff_betas_8months_ago = coeff_betas_updated)? Can this test be done in Stata? Thank you all.
Best wishes,
Miguel Valencia-Garza
