I am performing fixed effects panel regression and some of my control variables have outliers.
For eg:
Code:
univar land_amount
-------------- Quantiles --------------
Variable n Mean S.D. Min .25 Mdn .75 Max
-------------------------------------------------------------------------------
land_amount 5734 1.87 4.17 0.00 0.02 0.55 2.50 100.00
-------------------------------------------------------------------------------Code:
tab land_amount
land_amount | Freq. Percent Cum.
