We discuss briefly the very interesting concept of Brownian distance covariance developed by Sz\'{e}kely and Rizzo [Ann. Appl. Statist. (2009), to appear] and describe two possible extensions. The first extension is for high dimensional data that can be coerced into a Hilbert space, including certain high throughput screening and functional data settings. The second extension involves very simple modifications that may yield increased power in some settings. We commend Sz\'{e}kely and Rizzo for… Expand
We extend the theory of distance (Brownian) covariance from Euclidean spaces, where it was introduced by Székely, Rizzo and Bakirov, to general metric spaces. We show that for testing independence,Expand
The distance correlation t-test of independence in high dimension
A modified distance correlation statistic is proposed, such that under independence the distribution of a transformation of the statistic converges to Student t, as dimension tends to infinity, and the resulting t-test is unbiased for every sample size greater than three and all significance levels.

An Inaugural Dissertation
A task in statistics is to find meaningful associations or dependencies between multivariate random variables or in multivariate, time-dependent stochastic processes. Hawkes (1971) introduced theExpand
Tests of Mutual or Serial Independence of Random Vectors with Applications
Empirical rejection rates obtained through extensive simulations confirm both the applicability of the testing procedures in small samples and the high level of competitiveness in terms of power. Expand
An Updated Literature Review of Distance Correlation and Its Applications to Time Series
The concept of distance covariance/correlation was introduced recently to characterize dependence among vectors of random variables. We review some statistical aspects of distanceExpand

A modification to the RV coefficient is proposed, and used to construct a test of significance for the true coefficient, which improves the accuracy of the original and can be applied to data with arbitrarily large dimensions, possibly exceeding the sample size, and the underlying distribution need only have finite fourth moment.

Efficient test for nonlinear dependence of two continuous variables
This work proposed a new way of testing nonlinear dependence between two continuous variables (X and Y) by using CANOVA (continuous analysis of variance, software available at https://sourceforge.net/projects/canova/). Expand
Using distance covariance for improved variable selection with applications to genetic risk models
A property for distance covariance is demonstrated, which is incorporated in a novel feature screening procedure together with the use of distance correlation, which makes no distributional assumptions for the variables and does not require the specification of a regression model. Expand
A Statistical Approach for Testing Cross-Phenotype Effects of Rare Variants.
A statistical method for cross-phenotype analysis of rare variants using a nonparametric distance-covariance approach that compares similarity in multivariate phenotypes to similarity in rare-variant genotypes across a gene is introduced. Expand
Bagging Nearest-Neighbor Prediction independence Test: an efficient method for nonlinear dependence of two continuous variables
This work proposed an efficient method for nonlinear dependence of two continuous variables (X and Y) by using BNNPT (Bagging Nearest-Neighbor Prediction independence Test, software available at https://sourceforge.net/projects/bnnpt/). Expand


Brownian distance covariance
Distance correlation is a new class of multivariate dependence coefficients applicable to random vectors of arbitrary and not necessarily equal dimension. Distance covariance and distance correlationExpand
Measuring and testing dependence by correlation of distances
Distance correlation is a new measure of dependence between random vectors. Distance covariance and distance correlation are analogous to product-moment covariance and correlation, but unlike theExpand
