本文研究了移位模型G(x)= F(x+θ)中Mann-Whitney检验的功效,其中G的分布是通过将F移位θ得到的。使用Bootstrap方法来评估Mann-Whitney检验的功效。Bootstrap检验效能、Mann-Whitney检验的渐近效能和t检验效能之间的比较证明Bootstrap是一种更好的技术,因为它不需要正态性假设。
In this paper we evaluate the power of the Mann-Whitney test in the shift model G(x) = F (x+θ) for all x , where the distribution of G is obtained by shifting F by an amount of θ. The bootstrap method was used to evaluate the power of the Mann-Whitney test . A comparison among the bootstrap power , the asymptotic power of the Mann-Whitney test and the t-test power proved that the bootstrap is a better technique , because , it does not require the assumption of normality.
