Discreet.entropy_cs — MethodChao-Shen (2003) entropy estimator.
Discreet.entropy_shrinkage — MethodShrinkage entropy estimator.
Discreet.estimate_entropy — MethodEstimate the entropy of an array using a naive (frequencies-based), Chao-Shen, or shrinkage estimator. Chao-Shen and shrinkage estimators reduce the bias for small samples and a large number of classes.
