Tests of homogeneity for spatial populations

Statistics & Probability Letters, 2002, vol. 58, issue 2, 123-130

Abstract: We consider the problem of testing the homogeneity hypothesis in an RxC contingency table when the data are spatially autocorrelated. We show that familiar asymptotic results are invalid under these circumstances and we propose a simple adjustment to the standard [chi]2 statistic that allows for spatial dependence.
