Calculate Mann Whitney U statistic

Kev3 — Thu, 02 Nov 2017 20:33:25 GMT

How do I calculate the Mann Whitney U statistic? There is not a direct output from PROC NPAR1WAY.

PROC NPAR1WAY data=new wilcoxon;
    class Gender;
    var Variable;
    exact wilcoxon;
   run;

Thanks!

Hello,

The Wilcoxon rank-sum test is the same as the Mann-Whitney U test, so while SAS does not report a Mann-Whitney U statistic, the results are the same as the Wilcoxon rank-sum test.

I need to report to the U statistic. Should I just use SPSS?

As far as I know, SAS doesn't report the U statistic itself. If you need the U statistic specifically and have access to other stats packages that report it, I would use that just to be safe.
