摘要：
We show that the power functions of a class of nonparametric tests for the equality of two scale parameters do not approach 1 as the ratio of the parameters approaches infinity. The class of tests, known as linear rank tests, is shown to have a fundamental flaw when applied to scale parameters, resulting in low power when the sample sizes are small.
