Dear Stata community,

Im currently analizing travel times for serveral urban bus trips in
the city of Santiago, Chile. I'm using lots of data coming from GPS

Pretty newbie to Stata,  Im stuck trying to filter data by bus trip
route codes; Id like to drop all observations wich have travel times
under percentile 10 and over percentile 90 for all observations
sharing a certain route code... this filter for all route codes.

How could I do this?

Thank you in advance.
