Abstract
The numerator sum of squares in the conventional F-statistic for testing a linear hypothesis in a general linear model can be viewed as following the heuristic that K. Pearson used in his seminal 1900 paper. That is, find a statistic \(\varvec{U}\) that has expected value \(\varvec{0}\) under the null hypothesis and form from it \(\varvec{U}^{\prime }[\mathrm {Var}(\varvec{U})]^{-1}\varvec{U}\), which, if \(\varvec{U}\) is approximately normal, can be approximated as a chi-squared random variable. The class considered here comprises all such statistics based on linear statistics that have expected value \(\varvec{0}\) under the null hypothesis. Dominance relations among this class in terms of power are examined, and a complete subclass is described.
