WebJun 15, 2024 · Now I want to run a cross-sectional regression in Fama-MacBeth (1973) fashion. I don't understand how to proceed with this. In particular, I understand that the previously estimated betas become new explanatory variables. But what is not clear to me is: is there any other explanatory variable? how to correctly specify the dependent variable? In statistics and econometrics, a cross-sectional regression is a type of regression in which the explained and explanatory variables are all associated with the same single period or point in time. This type of cross-sectional analysis is in contrast to a time-series regression or longitudinal regression in which the variables are considered to be associated with a sequence of points in time.
