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: 为...

The notation for the chi-square distribution is:χ∼χ2dfχ∼χdf2where df = degrees of freedom which depends on how chi-square is being used. (If you want to practice calculating chi-square probabilities then use df=n−1df=n−1. The degrees of freedom for the three major uses ...

The distribution of the chi-square statistic is called the chi-square distribution. In this lesson, we learn to compute the chi-square statistic and find the probability associated with the statistic. And we'll work through some chi-square examples to illustrate key points. ...
