Tsallis.sd: Tsallis.sd

In EntropyEstimation: Estimation of Entropy and Related Quantities

Tsallis.sd

Description

Returns the estimated asymptotic standard deviation for the Z estimator of Tsallis Entropy. Note that this is also the asymptotic standard deviation of the plug-in estimator. See Zhang and Grabchak (2014a) for details.

Usage

Tsallis.sd(x, r)

Arguments

x	Vector of counts. Must be integer valued. Each entry represents the number of observations of a distinct letter.
r	Order of Tsallis entropy. Must be a strictly positive real number. Not allowed to be 1, in that case use Entropy.sd instead.
