What software implements the multiple comparison sign test as described in Steel (1959)?

    Which software are you using? Googling around let me find out that SYSTAT and SPSS in version 11.5 seem to have built in the Steel–Dwass–Critchlow–Fligner-test, an generalization of the test in your reference. There is an SUGI paper by Paul Juneau that mentiones a SAS macro called %DSCF that computes the test and can obviously only obtained by contacting the author. – psj Jun 12 '12 at 15:28
  • I wonder whether this is not simply the same think as a pairwise Wilcoxon rank test? If this is the case, one such test is implemented in R (in the default bundle) under the function pairwise.wilcox.test() – user603 Jun 13 '12 at 08:21

    @user603 That's a good guess, but those tests are not the same. The closest test that's widely implemented appears to be the [Kruskal-Wallis test](http://en.wikipedia.org/wiki/Kruskal%E2%80%93Wallis_one-way_analysis_of_variance) followed by some form of nonparametric multiple comparisons. – whuber Jun 13 '12 at 14:21
