基于渐进和重抽样二项分布的等价性检验

his paper discusses equality test of proportions in k (k≥2) independent binomial distributions on the basis of likelihood-ratio, score and Wald-type statistics via asymptotic, MaxT, MinP and Step-down methods. The performance of these test statistics are investigated with respect to the type I error rates and powers under various settings of parameters. Empirical results show that MaxT and MinP methods behave satisfactorily in the sense that their type I error rates are close to the pre-specified nominal level. An example is used to illustrate the proposed methodologies.
