## Functions to calculate the GiniSimpson index

### Description

GiniSimpson calculates the unbiased estimator, GiniSimpsonVar computes Gini-Simpson asymp- totic variance, and GiniSimpsonMVUE calculates the minimum variance unbiased estimator of the Gini-Simpson index.

### Usage

    GiniSimpsonMVUE(w)
    GiniSimpsonVar(w)

### Arguments

`w` | Vector of observed counts or frequencies.

### Value

A value that corresponds to the Gini-Simpson diversity index.
