Re: st: Fama-MacBeth regressions
Thanks for sharing the article by R. Douglas Martin.
It is interesting because I am working on robustness of Fama-Macbeth tests
and the corresponding impact on the tests of CAPM.
I have come across one paper which, using least trimmed squares approach,
gets contradictory results to what FM tests find.
