Gorard: A function to compute Gorard's segregation index
Description
Gorard's index is an alternative to ISDuncan's
index, which measures the dissimilarity between the distribution of a
group and the total population.
Usage
Gorard(x)
Value
a numeric vector containing the Gorard's segregation index value for
each group
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
totals because this will be interpreted as a group
