Rao: Functions to compute Rao’s entropy

In VHIRHepatiques/QSutils: Quasispecies Diversity

Functions to compute Rao’s entropy

Description

Set of functions to estimate Rao’s functional entropy. Rao calculates the Rao entropy, RaoVar the variance of the Rao estimator, RaoPow the Rao entropy of order q, and RaoPowProfile the functional Rao entropy profile for the given set of exponents.

Usage

Rao(dst, w=NULL)
RaoVar(dst,w=NULL)
RaoPow(dst,q,w=NULL)
RaoPowProfile(dst,w=NULL,q=NULL)

Arguments

dst	A "dist" object, output of the DNA.dist function.
w	An optional numeric vector with the haplotype counts. When w is NULL the same weight is given to each haplotype.
q	Exponent. A single value for Rao, RaoVar and RaoPow. A vector of values for RaoPowProfile. The default value for RaoPowProfile is a set of exponents to obtain a smooth profile.

Value

A single value for Rao, RaoVar and RaoPow. A vector of values for RaoPowProfile corresponding to each exponent in vector q.
