st: save p-values from Kruskal-Wallis-test

["BBS Querschnittsprojekt: Gerhard Sch�n" <bbs.methode@charite.de>]

Dear all,

I have to save p-values from a Kruskal-Wallis-test. 
Unfortunately the command kwallis doesn't return p-
values.

. sysuse auto
. kwallis price, by(foreign)
. return list

Is there a way to obtain p-values from Kruskal-Wallis-
test in a (e)return list; maybe within other commands?

Thanks,
Gerhard
