I'm doing non-parametric tests on paired (pre/post) samples that are ordinal (7-point Likert) and non-normally distributed, therefore using PROC UNIVARIATE with the difference of Time1 and Time2. I know that the test statistic in the SAS output (Singed Ranked, S) is the Wilcox Signed Rank test with its corresponding P value. But it seems like, for the sake of reporting in a manuscript, the literature uses "W" which doesn't seem to be the same test statistic. Do you know how to get this W or do you think I should report the S? (S=-387.5, p<.0001). Thanks!
