Space-time clustering tests for more than two samples.
The two-sample randomization tests for space-time clustering of Klauber are extended to cases with more than two samples. The approach is that of Mantel's one-sample test. The q-sample test provides the opportunity to test up to 2q-1 different models, depending on which of one or more of the q samples are considered random. A normal approximation is provided. An example using contrived data is used to illustrate the computations. An additional example using actual human, canine and feline leukemia and lymphoma is provided, and for this example an "analysis of clustering" table, comparable to tables for the analysis of variance is shown.
