Energy-Based Dependence Measures
Description
EDMeasure: A package for energy-based dependence measures
Details
The EDMeasure package provides measures of mutual dependence and tests of mutual independence, independent component analysis methods based on mutual dependence measures, and measures of conditional mean dependence and tests of conditional mean independence.
The three main parts are:
mutual dependence measures via energy statistics
measuring mutual dependence
testing mutual independence
independent component analysis via mutual dependence measures
applying mutual dependence measures
initializing local optimization methods
conditional mean dependence measures via energy statistics
measuring conditional mean dependence
testing conditional mean independence
Mutual Dependence Measures via Energy Statistics
Measuring mutual dependence
The mutual dependence measures include:
asymmetric measure
\mathcal{R}_nbased on distance covariance\mathcal{V}_nsymmetric measure
\mathcal{S}_nbased on distance covariance\mathcal{V}_ncomplete measure
\mathcal{Q}_nbased on complete V-statisticssimplified complete measure
\mathcal{Q}_n^\starbased on incomplete V-statisticsasymmetric measure
\mathcal{J}_nbased on complete measure\mathcal{Q}_nsimplified asymmetric measure
\mathcal{J}_n^\starbased on simplified complete measure\mathcal{Q}_n^\starsymmetric measure
\mathcal{I}_nbased on complete measure\mathcal{Q}_nsimplified symmetric measure
\mathcal{I}_n^\starbased on simplified complete measure\mathcal{Q}_n^\star
Testing mutual independence
The mutual independence tests based on the mutual dependence measures are implemented as permutation tests.
