Stata

I'm trying to do as much as I can with R instead of Stata, but Stata has positive network externalities in the economics profession and it's hard to move away if you have coauthors using it. Anyway, one of the most common regressions I have to run is a fixed effects regression with clustered standard errors. Suppose that Y is your dependent variable, X is an explanatory variable and F is a categorical variable that defines your fixed effects.
