%description
Functions related to multivariate measures of independence and ICA:
-estimate independent components by minimizing distance covariance;
-conduct a test of mutual independence based on distance covariance;
-estimate independent components via infomax (a popular method but
generally performs poorer than mdcovica, ProDenICA, and/or fastICA, but is
useful for comparisons); -order indepedent components by skewness; -match
independent components from multiple estimates; -other functions useful in
ICA.
