KS test
A non-parametric test of the equality of continuous, one-dimensional probability distributions that can be used to compare a sample with a reference probability distribution (one-sample K–S test), or to compare two samples (two-sample K–S test). The distributions considered under the null hypothesis are continuous distributions but are otherwise unrestricted.
