摘要
p值法是假设检验中常用的统计方法,总结了几种常用分布的概率密度函数,讨论了利用概率密度积分法求解P值,并以χ2分布为例,给出算法实现的关键程序代码。
P value method is frequently used in hypothesis test.In this paper, the author summarizes several probability density function of distributions, then discusses how to calculate P value by integral on them.At last,the paper lists some program code of X^2 distribution.
