      We consider computation of statistical dependence measures that are based on pairwise distances. Distance correlation had been introduced as a better alternative to the celebrated Pearson’s correlation. The existing algorithm for the distance correlation seemingly requires an O(n^2) algorithm, and I will show how it can be done in O(n log n). Moreover, many other statistical dependency related quantities can be computed efficiently. I will give some other examples. This talk is based on a joint work with Dr. Gabor Szekely.
