Doubtful, likely only because the wilcoxon_test function is already in Octave core, and it covers some of the same functionality.

If ranksum were added to the statistics Octave Forge package, we could deprecate the wilcoxon_test function in core.

ranksum is a function in the statistics toolbox of Matlab. Shouldn't the ranksum function be added to the statistics package of Octave Forge, rather than core Octave? Or is there some other reason why it should be in core?

The funktion "ranksum" is missing in Octave. Octave's alternative "wilcoxon_test" does not support method "exact", whis is important for small sample sizes (n < 25).
