Thread-topic: [S] Comparing Medians with SPlus
One approach is to load the resample library and use the permutationTest2 function to compare the medians.

Subject: [S] Comparing Medians with SPlus

Dear all,
I am new to SPLUS and  I would like to ask your help with the following topic. I have three sets of numeral data, 2 sets are paired and a third is independent of the other two. For each of these sets I have obtained their basic statistics (mean, median, stdv, range ...).
Now I want to compare if these sets differ. I could compare
the mean doing a basic T test . However, I was looking for a test to compare the medians using SPLUS.   If that is possible I would love to
hear the specifics.
Thank u !
 
Samir
