Score tests are among the most powerful of tests for focused clustering. However, their dependency on a chosen stochastic model and specific parameterization of the exposure indicates that they will be inefficient if these assumptions are far from the truth. To address the parameterization of the exposure, we develop maximin efficiency robust tests (MERTs) for candidate sets of possible exposures. The power of several MERTs and single tests are compared through simulation. We then examine the power of our MERTs and single tests for a departure from the usual Poisson stochastic model, namely, the zero-inflated or Poisson with added zeros model. Variations of the tests, adequate for this model, are proposed. Finally, we present an application of the methods to leukemia incidence data from upstate New York.Subjects--Topical Terms:
