[R-pkgs] copent: Estimating Copula Entropy

[Ma Jian]

Hi all,


I'm writing to you to introduce our new package, copent. This package estimates copula entropy, a new mathematical concept for multivariate statistical independence measure and testing [1].  The estimating method is nonparametric and can be applied to any cases without making assumptions. The package has been used for 
 * association discovery [2], in which copula entropy is an association measure shown to be better than correlation coeffients,
 * structure learning [3],
 * variable selection [4], and 
 * causal discovery [5] by estimating transfer entropy.

Hope it helpful for you. Any comments and suggestions are welcome.


Best Regards,
MA Jian
