<p dir="auto">Sparse matrices are a very interesting data model for graphs or edges-only meshes. But using float dtype spends too much place where we only need boolean information. So, an extension of this module, with dtypes bool (and maybe int8/int16/int32) would be really useful.</p>
<p dir="auto">I can help work on this topic.</p>

<p dir="auto">For an experiment, I first performed the Wilcoxon Rank Sum Test (of Scipy) and now I would like to report the measured effect-size.</p>
<h3 dir="auto">Describe the solution you'd like.</h3>
<p dir="auto">For non-normal distributed data, that has a Wilcoxon-RankSum-Test proven difference common tests would be Vargha-Delaney or Cliff's Delta <a href="https://en.wikipedia.org/wiki/Effect_size" rel="nofollow">e.g. from Wikipedia</a></p>
<h3 dir="auto">Describe alternatives you've considered.</h3>
<p dir="auto">There are some Gist-Implementations and Snippets found online, that will do the trick.</p>
