I have a quick question regarding the quintiles. I used the
command xtile listed in the manual under pctile to divide income into
quartiles. What I want to know is the the highest value in each
quartile. I tried to sort and list, but the data is too big to list
all the values. Anyone has a more convenient way to do it?
sysuse auto,clear
xtile pct = mpg, nq(5)
bys pct (mpg): l mpg if _n==_N
// or
sort pct mpg
by pct: g hival = mpg if _n==_N
l pct hival if !mi(hival)
