[Gretl-users] Wilcoxon.gfn package: removal and alternative

Hi all, the contributed function package Wilcoxon.gfn is going to be removed from the server soon. Gretl covers the functionality (the signed rank Wilcoxon test) with the built-in command 'difftest'. Example usage for series x and y (see also the difftest help): difftest x y --signed-rank And you can retrieve the results via the usual $test and $pvalue accessors. If you need a functional form, you could use something like this trivial wrapper: <hansl> function scalar wilcoxonreplacement(series x, series y) difftest x y --signed-rank return $test end function </hansl> In the graphical interface (GUI) you would go to: Tools/Nonparametric tests/ Difference test. Happy testing, Sven
