Stata's didregress and xtdidregress commands fit DID and DDD models that control for unobserved group and time effects. didregress can be used with repeated cross-sectional data, where we sample different units of observations at different points in time. xtdidregress is for use with panel (longitudinal) data. These commands provide a unified ...Stata's Fisher panel unit root test in doesn't allow to automatically select the optimal lag.
