WebA measure of dependence between two random variables. Unlike Pearson Product Moment correlation, distance correlation measures strength of association between the … WebMay 6, 2008 · Reassuringly, we found that differences in auto-correlations between the 64×64 torus and exact calculations were never greater than 3×10 −5, which occurred at the maximum distance considered of 20 km, and this reduced to 10 −7 when using a 128×128 torus. We conclude that results are insensitive to the torus approximation.

In statistics and in probability theory, distance correlation or distance covariance is a measure of dependence between two paired random vectors of arbitrary, not necessarily equal, dimension. The population distance correlation coefficient is zero if and only if the random vectors are independent. Thus, distance … See more The classical measure of dependence, the Pearson correlation coefficient, is mainly sensitive to a linear relationship between two variables. Distance correlation was introduced in 2005 by Gábor J. Székely in several lectures to … See more Distance covariance Let us start with the definition of the sample distance covariance. Let (Xk, Yk), k = 1, 2, ..., n be a statistical sample from a pair of real valued … See more Distance covariance can be generalized to include powers of Euclidean distance. Define Then for every See more Other correlational metrics, including kernel-based correlational metrics (such as the Hilbert-Schmidt Independence Criterion or HSIC) can also detect linear and nonlinear … See more Distance correlation 1. $${\displaystyle 0\leq \operatorname {dCor} _{n}(X,Y)\leq 1}$$ and $${\displaystyle 0\leq \operatorname {dCor} (X,Y)\leq 1}$$; … See more Brownian covariance is motivated by generalization of the notion of covariance to stochastic processes.
