histogram.cliffsD(other)

• other <Histogram> 用来比较的直方图。
• 返回：<number> 一个介于 -1.0 和 1.0 之间的值。

计算 克利夫的德尔塔，一种非参数效应量度。返回的是这个直方图中随机值超过 other 中随机值的概率减去相反概率。值为 1 表示这个直方图中的每个值都超过 other 中的每个值；-1 表示相反；0 表示没有任何倾向。

🌐 Computes Cliff's delta, a non-parametric effect size measure. Returns the probability that a random value from this histogram exceeds a random value from other, minus the reverse probability. A value of 1 means every value in this histogram exceeds every value in other; -1 means the opposite; 0 means no tendency in either direction.
