Re: RE: st: AW: Create a flag variable for 10 most frequent values

[gjhxmu@sina.com]

Suppose we need to flag the 5 most frequent values, how about the following typings?

sysuse auto, clear
keep mpg
bys mpg: egen mycount=count(mpg)
bys mycount: g num=_n
gsort num -mycount
g tag=_n<=5
bys mycount: egen rank5=max(tag)


Hope it helps!
