全距檢定法是在檢定二項分配比例與波氏分配參數等價假設，相對於對立假設則為不等價。為了消除變異數未知情況，使用了二項及波氏隨機變數兩者的變異數穩定轉換，在最保守參數均數組合下，關於這些假設檢定的最大水準和最小檢定力趨近於常態定理。在給予水準與檢定力下，實驗的臨界值和所須的樣本數可以被同時決定，而電腦程式也在此目的下形成。

A range test is proposed for testing the hypothesis of equivalence of binomial proportions and Poisson parameters, respectively against the alternative hypothesis of inequivalence. Variance stabilization
transformations for both binomial and Poisson random variables are used to remove unknown parameters in the variances. Both the maximum level and the minimum power of the proposed test associated with these hypotheses can be approximated by normal theory at the corresponding least favorable configurations of parameters. For a given level and a given power, the critical value and the required
sample size for an experiment can be simultaneously determined, and a computer program is developed for such purpose.
