Description

Multi-group dissimilarity index, is a multi-group version of Duncan's dissimilarity index (DIDuncan)

Usage

1
DMulti(x)

Arguments

x

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