CMulti: A function to compute multigroup squared coefficient of variation index
Description
The index can be interpreted as a measure of the variance of the
spatial representation of the groups accros spatial unite, or as a normalized
chi-squared measure of association between groups and units.
Usage
CMulti(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.
Value
Multigroup entropy segregation index
