st: RE: Multiple comparison: non-parametric test
The -smileplot- package, downloadable from SSC, can calculate P-values
adjusted for multiple comparisons. In Stata, type
ssc describe smileplot
to find out more. There is also a Stata Journal draft about -smileplot-
(Newson et al., 2003), and a Stata User Meeting presentation about
-smileplot-, downloadable on my website (see my signature below).
For more about the parameters underlying so-called "nonparametric"
statistics, Siddharth might like to refer to Newson (2002). A draft of
this can also be downloaded from my website.
I hope this helps.
Best wishes
Roger

Subject: st: Multiple comparison: non-parametric test
is there a way to calculate adjusted p-values for a non-parametric test
(rank-sum) in stata?
If not, what is the alternative?
Thanks,
Siddharth.
