Subject:      Wilcoxon test for Gender by product
Content-Type: text/plain; charset=iso-8859-1

I need to do Wincoxom test among certain Gender (for ex Female) by product (for ex Comm and Medicare). I used the following code:

  proc NPAR1WAY data=out.baseline Wilcoxon;
  by gender product;
  var emotional_score_f physical_score_f total_score_f;
  title 'Wilcoxon Test between Gender by Product for Baseline';
  run;

  However I got the following Error log:

  5          proc NPAR1WAY data=out.baseline Wilcoxon;
  INFO: Data set OUT.BASELINE.DATA is in a foreign host format. Cross Environment Data Access will be used, which may require
  additional CPU resources and reduce performance.
  6          by gender product;
  7          var emotional_score_f physical_score_f total_score_f;
  8          title 'Wilcoxon Test between Gender by Product for Baseline';
  9          run;

  ERROR: One and only one CLASS variable must be specified.
  ERROR: One and only one CLASS variable must be specified.
  ERROR: One and only one CLASS variable must be specified.


  How can I do it in a  proper syntax?

  Thank you in advance!
