g-text">(permutation-test xs ys &amp;opt a k)

Conducts a permutation test to determine if two data sets
`xs` and `ys` are *significantly* different from each other.
You can use alternative hypothesis `a`, which defaults to `:two-side`,
with `:greater` and `:lesser` being the other two options.
The last optional argument is `k` number of values
in permutation distribution</pre></div><hr><div class="binding"><span id="math/permutations" class="binding-sym">math/permutations</span> <span class="binding-type">
