The Wald–Wolfowitz runs test (or simply runs test), named after statisticians Abraham Wald and Jacob Wolfowitz is a non-parametric statistical test that checks a randomness hypothesis for a two-valued data sequence. More precisely, it can be used to test the hypothesis that the elements of the sequence are mutually independent.

WebbRuns Test for Randomness. Performs a test whether the elements of x are serially independent - say, whether they occur in a random order - by counting how many runs there are above and below a threshold.
