Hi Hongjian,
Thanks so much for your reply. But I'm still so confused about this. You know,
if we select F-test, that means I want to find the difference between
regressors, which should be two-way difference. Whereas, If I select t-test,
that means I want to find the one-way difference. The resulting results are con*
file (if t-test) and ess* file (if F-test). If I select F-test, there is no con*
file in the directory. I may misunderstand your meaning. If so, could you let me
know more? Thanks so much!
Best regards,
