针对单侧假设检验中出现的自相矛盾的决策问题,在简单分析单侧假设检验两类错误具体形式的基础上,给出了检验决策可信度的概念及其计算公式,并提出了用决策可信度来判断单侧检验原假设及其结论是否有效的方法.实例表明,方法是可行的,有效的.
In this paper,The notions of the credibility and its formulation are given by the two types of errors and the decision theory of the hypothesis testing,and a method has been proposed to determine the validity of Null hypothesis of one side hypothesis testing and it’s conclusion.It shows that is effective with an example.
