【摘要】 本文通过实例分析,说明对于给定的统计检验模型应根据实际问题的使用与经济价值区别不同情况,合理地控制犯第一类错误与第二类错误的概率以及样本容量,从而去确定最优拒绝域。而不应笼统地采用现行的传统做法,即通常限定第一类错误的概率(显著水平)的前提下,去寻求最优拒绝域。更多还原

【Abstract】 Through analyzing the practical examples, this paper proves that the given statistical inspection model can reasonably control not only the probability to commit the first error and the second error but also the sample capacity on the basis of different practical problems about the use value and the economical one, thus determining the optimum rejection region. It is inadvisable that by adopting the present traditional method, i.e. under the requisites for limiting the probability of the first error ( notable level) , the optimum rejection region is being explored.更多还原
