（重定向自Cumulative probability distribution function）
累积分布函数，又叫分布函数，是概率密度函数的积分，能完整描述一个实随机变量X的概率分布。一般以大写“CDF”（Cumulative Distribution Function）表记。
对于所有实数x ，累积分布函数定义如下：

In probability theory and statistics, the cumulative distribution function (CDF) of a real-valued random variable X, or just distribution function of X, evaluated at x, is the probability that X will take a value less than or equal to x.
In the case of a continuous distribution, it gives the area under the probability density function from minus infinity to x. Cumulative distribution functions are also used to specify the distribution of multivariate random variables.
