两个对数正态分布均值差的推断:一种推广的方法
Inference on Difference of Means of two Log-Normal Distributions; A Generalized Approach
摘要:
在过去的几十年里,已经提出了各种方法来比较两个对数正态分布的均值。其中一些在统计检验如何调整以接受或拒绝原假设方面是不同的。本文利用广义证据量,给出了一种新的检验方法,用于比较两个对数正态总体的均值,以反对原假设。然而,这种方法的计算是简单的,我们发现,分析所考虑的方法是做得很好,通过比较的大小和功率统计检验。除了模拟,一个例子与真实的数据进行了说明。
英文摘要:
Over the past decades, various methods for comparing the means of two log-normal have been proposed. Some of them are differing in terms of how the statistic test adjust to accept or to reject the null hypothesis. In this study, a new method of test for comparing the means of two log-normal populations is given through the generalized measure of evidence to have against the null hypothesis. However calculations of this method are simple, we find analytically that the considered method is doing well through comparing the size and power statistic test. In addition to the simulations, an example with real data is illustrated.
