Gini R Documentation
A function to compute Gini's segregation index
Description
The segregation version of the Gini index can be derived from
the Lorenz curve as the area between the segregation curve and the
diagonal.
Usage
Gini(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
A numeric vector containing Gini's segregation index values for each group
