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. CRAN: https://cran.r-project.org/package=copent GITHUB: https://github.com/majianthu/copent/ Hope it helpful for you. Any comments and suggestions are welcome.
