BerryMielke {agrmt}

Calculate IOV

Description

Calculate Berry and Mielke's IOV.

Usage

BerryMielke(V)

Arguments

V

A frequency vector

Details

This function calculates Berry and Mielke's IOV, a measure of dispersion based on squared Euclidean distances. This function follows the presentation by Blair and Lacy 2000, but includes the adjustment for Tmax omitted by Blair and Lacy as there is no reason to leave it out. The derived measure COV by Kvalseth is implemented as Kvalseth. Usually, the IOV is equivalent to 1-lsquared.

Value

The function returns the IOV.
