Squared ranks test
In statistics, the Conover squared ranks test[1][2] is a non-parametric version of Levene's test for equality of variance. This becomes important when the Levene's test fails to satisfy the rather generous conditions for normality associated with that test and is a default alternative under those conditions for certain statistical software programs like the VarianceEquivalenceTest[3] routine in Mathematica.
