The problem of testing equality of two independent binomial proportions is reexamined. A recent article by D’Agostino, Chase, and Belanger (1988) argues that the Fisher exact test and the Yates chi-squared test with continuity correction are much too conservative in small samples. The authors proposed using a studentized version of the Pearson chi-squared test, and… Continue reading Testing the equality of two independent binomial proportions.

To model or not to model? Competing modes of inference for finite population sampling
Finite population sampling is perhaps the only area of statistics in which the primary mode of analysis is based on the randomization distribution, rather than on statistical models for the measured variables. This article reviews the debate between design-based and model-based inference. The basic features of the two approaches are illustrated using the case of… Continue reading To model or not to model?
