EDMeasure: A package for energy-based dependence measures
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
Measuring mutual dependence
The mutual dependence measures include:
asymmetric measure \mathcal{R}_n based on distance covariance \mathcal{V}_n
symmetric measure \mathcal{S}_n based on distance covariance \mathcal{V}_n
complete measure \mathcal{Q}_n based on complete V-statistics
simplified complete measure \mathcal{Q}_n^\star based on incomplete V-statistics
asymmetric measure \mathcal{J}_n based on complete measure \mathcal{Q}_n
simplified asymmetric measure \mathcal{J}_n^\star based on simplified complete measure \mathcal{Q}_n^\star
symmetric measure \mathcal{I}_n based on complete measure \mathcal{Q}_n
simplified symmetric measure \mathcal{I}_n^\star based 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.
