Class-Specific Tests of Spatial Segregation Based on Nearest Neighbor Contingency Tables
Elvan Ceyhan
The spatial interaction between two or more classes (or species) has important consequences in many fields and might cause multivariate clustering patterns such as segregation or a…
On the Use of Nearest Neighbor Contingency Tables for Testing Spatial Segregation
Elvan Ceyhan
For two or more classes (or types) of points, nearest neighbor contingency tables (NNCTs) are constructed using nearest neighbor (NN) frequencies and are used in testing spatial se…
Overall and Pairwise Segregation Tests Based on Nearest Neighbor Contingency Tables
Elvan Ceyhan
Multivariate interaction between two or more classes (or species) has important consequences in many fields and causes multivariate clustering patterns such as segregation or assoc…
A New Family of Random Graphs for Testing Spatial Segregation
E. Ceyhan, C. E. Priebe, D. J. Marchette
We discuss a graph-based approach for testing spatial point patterns. This approach falls under the category of data-random graphs, which have been introduced and used for statisti…
