st: Nonparametric Multiple Comparison Testing

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, Christopher Simpkins, M.D. Research Fellow Department of Surgery The Johns Hopkins University, School of Medicine
