Robust Copula Dependence for Multivariate and Conditional Dependence with Applications
Authors: ,
Abstract: Measures of statistical dependence is of great importance for machine learning and statistical models. Recently, a new measure, the robust copula dependence (RCD) is shown to be equitable in treating dependence of linear and nonlinear relationships. The paper propose extensions of RCD to multivariate and conditional cases, which is crucial for many applications. We study the theoretical and empirical properties of the extended RCD. We successfully apply to several example applications including learning delayed time in nonlinear systems, independence testing with mixture alternatives and feature selection.
