Gen tstat_`var' = car_`var'/(rmse_`var'*sqrt(_N))ĭrop returnmarket date_id evday evt_window dateġ) put a dummy variable in my regressions such that it identifies an event and assign a value of 0 on event date and 1 otherwise.Ģ) have several dummy variables for each of the event date in my sample.Īny ideas how I should proceed with that?
