| 摘 要： | 在统计的参数假设检验中,对可能作出的2个相互对立的假设,存在如何选择零假设的问题;而且对同一样本信息,由于零假设的不同选取,可能会得到不同的检验结论.分析了参数的显著性检验中由于零假设的不同选择所出现的问题,探讨了零假设的选择原则.

| Abstract: | In the statistical parameter hypothesis testing,there exists a problem of how to choose null hypothesis in mutual opposed two possible hypotheses.And to the same sample information,there may be different conclusions of parameter tests because of different choices of zero hypothesis.This paper analyzes the problem appearing in the parameter significance testing based on different choice of null hypothesis and discusses the choice principles of null hypothesis. |
