I think what you need is the -xtile- command. In Stata, type -help xtile- to find out more.

Hi guys,

i am completely new to stata and have a question regarding the
splitting of my dataset into percentiles.

I am examining the impact of migration on the wage distribution and am
considering variation over time
and regions (provinces). so for each province for each year i need the
different percentiles of wages. does anyone
know how to do this without splitting up the dataset in excel prior to
stata? I have been trying with the
-centile- function but i dont know how to tell stata to do that for
every year and every province and additionaly
to expand this to the control variables aswell.

thanks a lot!!!!
