Fama and French regressions, specifically in 1993 paper, are time-series, i.e., they develop portfolios and risk factors, then the time-series returns of each portfolio are regressed on the time series of risk factors. Abstract: xtfmb is an implementation of the Fama and MacBeth (J. Polit. The first stage 300 regressions are not useful, they are used just to obtain the average coefficients of the factors used in regressions. Dear fellow research colleagues, abstract xtfmb is an implementation of the Fama and MacBeth (J. Polit. The Fama-MacBeth procedure has been critized for several reasons. Login or Register. Econ. Since the regressions are cross-sectional, the factor must vary across cross sectional units. Econ.
