We derive statistics defined as divergences between unrestricted and restricted estimated joint cell probabilities and we show that they are asymptotically distributed as linear combinations of chi-square random variables under the null hypothesis of homogeneity. Monte Carlo simulation experiments are carried out to investigate the behavior of the new divergence test statistics and to make comparisons with the statistics that do not take into account the spatial correlation. We show that some of the introduced divergence test statistics have a significantly better behavior than the classical chi-square test for the problem under consideration when we compare them on the basis of the simulated sizes and powers.engjournal articlehttp://link.springer.com/article/10.1007%2Fs00362-013-0554-6restricted access519.22Test of homogeneityDivergence statisticsChi-square statisticSpatial dataEstadística matemática (Matemáticas)1209 Estadística
