Hi all,

I'm writing to you to introduce our new package, copent [6]. 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,
