unknown egen function xtile()

[Emma Gardner]

Hi there;

I tried to create quantiles on a dataset using egen and xtiles. Below is the code and error message returned.

. egen meantempQ3 = xtile(meantemp), p(33(33)67) by(stratum)
unknown egen function xtile()

After reading this post and this post I ran this:

. which xtile, all

/Applications/Stata/ado/base/x/xtile.ado
*! version 3.1.8  16feb2015

and this:

. adopath
  [1]  (BASE)      "/Applications/Stata/ado/base/"
  [2]  (SITE)      "/Applications/Stata/ado/site/"
  [3]              "."
  [4]  (PERSONAL)  "/Users/emma/Library/Application Support/Stata/ado/personal/"
  [5]  (PLUS)      "/Users/emma/Library/Application Support/Stata/ado/plus/"
  [6]  (OLDPLACE)  "~/ado/"

Any help, insight, or clues as to why the above error message would be appreciated. I'm using stata 15.

Many thanks, Emma

The search for xtile's code is not what is needed as the source code for any egen function foobar() would be in _gfoobar.ado although I don't know anyone is expected to know that unless they found it out for themselves.

You need to install using

ssc inst egenmore

Thank you!!

Note that

search xtile egen

does point in the right direction.
