# POST /wilcoxon/{alpha}

`POST /wilcoxon/{alpha}`

Calculate the Wilcoxon signed-rank test. <br/>The Wilcoxon signed-rank test tests the null hypothesis that two related paired samples come from the same distribution. In particular, it tests whether the distribution of the differences x - y is symmetric about zero. It is a non-parametric version of the paired T-test. <br/>More info in [STAC Python Documentation](http://tec.citius.usc.es/stac/doc/scipy.stats.wilcoxon.html).
