在这项研究中,假设检验,当既不是概率密度函数(pdf)的检验统计量下的零假设,也不知道的概率密度函数下的备择假设的检验统计量。首先,经典的过程中的情况下,随机变异性进行审查。然后,测试程序扩展到的情况下,测量的不确定度包括随机和系统误差。这两种类型的不确定性被处理在一个全面的方式使用模糊随机变量(FRV),代表概率和模糊理论的结合。随机误差(不存在系统误差)的经典情况是FRV的特殊情况。该程序的基本理论特别概述。该方法允许考虑接受和拒绝的模糊区域。最终的(最优的)测试决策是基于效用理论,选择具有最大期望效用的测试决策作为最有益的一个。一个例子说明了理论概念。
In this study hypothesis testing is treated, when neither the probability density function (pdf) of the test statistic under the null hypothesis nor the pdf of the test statistic under the alternative hypothesis are known. First, the classical procedure in case of random variability is reviewed. Then, the testing procedure is extended to the case when the uncertainty of the measurements comprises both random and systematic errors. Both types of uncertainty are treated in a comprehensive way using fuzzy-random variables (FRVs) which represent a combination of probability and fuzzy theory. The classical case of random errors (absence of systematic errors) is a special case of FRVs. The underlying theory of the procedure is outlined in particular. The approach allows the consideration of fuzzy regions of acceptance and rejection. The final (optimal) test decision is based on the utility theory which selects the test decision with the largest expected utility as the most beneficial one. An example illustrates the theoretical concept.
