摘要
贝叶斯学派对于P-值在假设检验中的应用有很大的争议。介绍了P-值在数理统计中的地位,分析了P-值的含义以及应该如何正确理解P-值。指出了P-值的优点及不足之处。最后给出了几何分布和均匀分布参数假设检验时P-值的计算公式。
Bayesians have a lot of controversy on p-values for such a long time.The role is introduced which played by p-values in mathematical statistics and analysis the meaning of p-value and discuss how to correctly understand p-value.Further more,the advantages and disadvantages has been summarized.Finally,two formulas is derived for calculating the p-value when testing the statistical hypotheses on the parameter of geometric distribution and uniform distribution.
