Abstract:
Summary. By focusing on a confidence interval for a nuisance parameter, Berger and Boos (1994, Journal of the American Statistical Association89, 10121016) proposed new unconditional tests. In particular, they showed that, for a 2 × 2 table, this procedure generally was more powerful than Fisher's exact test. This paper utilizes and extends their approach to obtain unconditional tests for combining several 2×2 tables and testing for trend and homogeneity in a 2 ×K table. The unconditional procedures are compared to the conditional ones by reanalyzing some published biomedical data.Keywords: Cochran-Armitage test; Cochran-Mantel-Haenszel test; Contingency tables; Exact inference; p-value; Unconditional test
