Is it possible to perform nonparametric multiple comparison testing in Stata?  I am attempting to compare the distributions of a continuous variable (AGE) between five groups (group5) with unequal variances (based upon Bartlett's test using the oneway command) and I don't see any option for multiple comparison testing with the kwallis command.  I searched through the Statalist archives and Stata's help but haven't been able to turn up any information on this.
 
Here are the commands that I used: 
 
oneway AGE group5, bonferroni 
 
kwallis AGE, by(group5) 
 
Thanks for your help,
