Hello
Use the .do file syntax method, and set your .do program to place the command
egen pctile etc.
coming before a keep command or a drop command - either way, using an if subcommand.
Thus you drop any data that is not on the relevant pctile.
Yours

Subject: 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
