GiniMulti: A function to compute multigroup Gini index

Description

GiniMulti is a multigroup version of the Gini index

Usage

GiniMulti(x)

Arguments

x

- an object of class matrix (or which can be coerced to that class), where each column represents the distribution of a population group, within spatial units. The number of columns should be greater than 1 (at least 2 population groups are required). You should not include a column with total population in each unit, because this will be interpreted as a group.
