Gini2: A function to compute Spatial Gini's between group index
Description
The between group version of Gini index is obtained
by computing the index for a subpopulation formed by each pair of groups
Usage
Gini2(x)
Value
a matrix with between group Gini index
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.
