CMulti {OasisR} | R Documentation |
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 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. |
Value
The multigroup entropy segregation index value (numeric)
