Re: st: Identify observations within a variable

[Nick Cox <njcoxstata@gmail.com>]

As I understand it you want to replace differing values by the most
commonly occurring value. This is just the mode and the -mode()-
function of the -egen- command should suffice.

It has supported string arguments too since birth.

That aside your question is an FAQ

Although understanding the principles there will do no harm, my guess
is that you don't need it given -egen-'s -mode().
