ed: Calculate alpha, beta and gamma true entropies and...

In MDM: Multinomial Diversity Model

Description

Calculates alpha, beta and gamma true diversities of a data set. The matrix or data frame is automatically scaled to row sums of one.

Usage

ed(x, q = 1, w = 1, retq = TRUE)

Arguments

x	the input matrix or data frame.
q	the order of diversity; typically 0, 1 or 2.
w	weights if required.
retq	if TRUE then diversities are returned; if FALSE the entropies for alpha and gamma are returned.

Value

a vector of entropies or diversities
