| Abstract: | 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 the meaning and level of significance of P value is analyzed and how to correctly understand P value is discussed.Further more,the advantages and disadvantages have 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. |
