"Conditional and unconditional tests for the extended Stuart-Maxwell de" by J. C.W. Rayner and D. J. Best
A design is given that includes the designs for the Stuart-Maxwell and Cochran tests. Two models, called the conditional and unconditional, are given for this extended design and the corresponding Wald-type test statistics derived. These test statistics differ by a simple constant but purportedly have the same asymptotic χ 2 null distribution. Since the unconditional test statistic is always larger than the conditional, if inference is based on their asymptotic χ 2 null distributions, the unconditional test will always be more critical of the null hypothesis. The test of Stuart is based on a...
