Web. matlab画CDF曲线 CDF(cumulative distribution function)叫做累积分布函数 描述一个实数随机变量X的概率分布,是概率密度函数的积分。 我觉得它的最主要作用就是观测某些数值也就是随机变量的取值在那个附近出现的概率比较大,它是一个增函数. Web. Para un valor t de x, la función de distribución acumulativa empírica F(t) es la proporción de los valores de x menor que o igual a t. I have a Matlab figure I want to use in a paper. As per my understanding, you are looking for the X axis values corresponding to Y axis values in ‘cdfplot’. That function allows you to specify that you are using a survival function.
