Gini2 {OasisR} | R Documentation |
A function to compute the between group version of segregation Gini 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)
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 matrix containing the between-group Gini index values for each pair of groups
