  "Description": "Implements various estimators of entropy for discrete\nrandom variables, including the shrinkage estimator by Hausser\nand Strimmer (2009), the maximum likelihood and the\nMillow-Madow estimator, various Bayesian estimators, and the\nChao-Shen estimator.  It also offers an R interface to the NSB\nestimator.  Furthermore, the package provides functions for\nestimating the Kullback-Leibler divergence, the chi-squared\ndivergence, mutual information, and the chi-squared divergence\nof independence.  It also computes the G statistic and the\nchi-squared statistic and corresponding p-values. Furthermore,\nthere are functions for discretizing continuous random\nvariables.",
