卡方分布(chi-square distribution, χ2-distribution)是概率统计里常用的一种概率分布,也是统计推断里应用最广泛的概率分布之一,在假设检验与置信区间的计算中经常能见到卡方分布的身影。 卡方分布的定义如下: 若k个独立的随机变量Z1, Z2,..., Zk 满足标准正态分布 N(0,1) , 则这k个随机变量的平方和: ...

The chi-square distribution is a family of curves that have the following properties: The curves areskewed right,unimodal, and have only non-negative values. Each curve is defined by itsdegrees of freedom. The mean of the distribution is equal to the number of degrees of freedom: μ =v. ...
