Description
Computes the Dixon's test of segregation for a bivariate pattern using
the nearest neighbour contingency table.
Usage
1
dixon(X, prepR = 0)
Arguments
X
Bivariate point pattern
prepR
Preparation range, eases nearest neighbour computation for huge patterns.
Details
The tests are an improvement on the Pielou's test of segregation. The test is defined only for two-type spatial pattern.
