累积机率 meaning in Chinese

cumulative probability

The probability of normal r . v . with absolute value less then and equal to one , two , and three unit standard deviations are calculated from error function , the cumulate probability distribution of normal density
常态分布随机变数绝对值小于等于一个、两个、三个标准差之机率分别代入累积机率分布函数(误差函数)算出其对应之机率。
The cumulative probability distribution ( cpd ) and probability density function ( pdf ) of the magnitude of signals with noise are approximated by the cumulate percentage distribution ( cpd ) and percentage density ( pcd ) respectively by sorting and discretizing . the simulation verfies the following
