The cumulative distribution function gives the probability that \(X\) is less than or equal to \(x\). 累积分布函数给出随机变量 \(X\) 小于或等于 \(x\) 的概率。
To compare two models, we plotted their cumulative distribution functions and found one assigns more probability to extreme values. 为了比较两个模型,我们绘制了它们的累积分布函数,发现其中一个对极端取值分配了更高的概率。
