We investigate different test procedures for testing the difference of two Poisson means. Asymptotic tests, tests based on an approximate p-value method, and a likelihood ratio test are considered. Size and power performance of these tests are studied by means of Monte Carlo simulation under different settings. If one wants to control the actual(More)
Inverse sampling suggests one continues to sample subjects until a pre-specified number of rare events of interest is observed. It is generally considered to be more appropriate than the usual binomial sampling when the subjects come sequentially, when the response probability is rare, and when maximum likelihood estimators of some epidemiological measures(More)
This article investigates various multiple testing procedures for the testing of unity odds ratios from stratified studies. These procedures compare individual ordered p-values to a series of adjusted nominal levels, and are employed to distinguish between significance and insignificance in stratified studies. Three commonly used approaches for determining(More)
