Betreff: st: Area under a percentile point
I have a simple question which I do not have the answer for. Is there
a way to tell Stata to keep the data under a certain percentile point
and drop the rest? This is important since in my data a percentile
point has often the same value as the ones below and over it.
Thanks
Zeynep Elitaş
