A Statistically and Numerically Efficient Independence Test Based on Random Projections and Distance Covariance

- Computer ScienceFrontiers in Applied Mathematics and Statistics
- 2021

A test of independence method based on random projection and distance correlation, which achieves nearly the same power as the state-of-the-art distance-based approach, works in the multivariate cases, and enjoys the O(nK log n) computational complexity and O( max{n, K}) memory requirement.

Measuring and testing dependence by correlation of distances

- Computer Science, Mathematics
- 2007

Distance correlation is a new measure of dependence between random vectors that is based on certain Euclidean distances between sample elements rather than sample moments, yet has a compact representation analogous to the classical covariance and correlation.

Equivalence of distance-based and RKHS-based statistics in hypothesis testing

It is shown that the energy distance most commonly employed in statistics is just one member of a parametric family of kernels, and that other choices from this family can yield more powerful tests.
