-The /WILCOXON subcommand tests for differences between medians of the
-variables listed.
-The test does not make any assumptions about the variances of the samples.
-It does however assume that the distribution is symetrical.
-
-If the @code{WITH} keyword is omitted, then tests for all
-combinations of the listed variables are performed.
-If the @code{WITH} keyword is given, and the @code{(PAIRED)} keyword
-is also given, then the number of variables preceding @code{WITH}
-must be the same as the number following it.
-In this case, tests for each respective pair of variables are
-performed.
-If the @code{WITH} keyword is given, but the
-@code{(PAIRED)} keyword is omitted, then tests for each combination
-of variable preceding @code{WITH} against variable following
-@code{WITH} are performed.
