摘要
本文介绍了经典统计学派(P值显著性水平)在数理统计中的地位,分析了P值及显著性水平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。并对两个学派的假设检验进行了比较和述评,给出了单参数假设检验时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 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.
