On combining independent tests in linear models

Scott M. Jordan and K. Krishnamoorthy

Statistics & Probability Letters, 1995, vol. 23, issue 2, 117-122

Abstract: The problem of testing the common mean of several normal linear models when the variances are unknown and unequal is considered. A minor modification to the combined tests given in Zhou and Mathew (1993a) is proposed. The powers of the modified tests are numerically compared with their original versions and a traditional test. Comparison studies indicate that the modified tests have better power properties than their original versions. Practical situations where the modified tests are preferable to the traditional test are pointed out.
