+shrinkage estimator by Hausser and Strimmer, the maximum likelihood and the
+Millow-Madow estimator, various Bayesian estimators, and the Chao-Shen
+estimator.  It also offers an R interface to the NSB estimator.  Furthermore,
+it provides functions for estimating Kullback-Leibler divergence, chi-squared,
+mutual information, and chi-squared statistic of independence.  In addition
+there are functions for discretizing continuous random variables.")
