Web我正在寻找一个包，它为非对称（偏斜）正态分布以及泊松和指数分布提供数学函数。 我最初查看了Colt包，但它没有提供反向累积函数。. 所以我改为Apache Commons Math3 … WebThe Poisson distribution is a one-parameter family of curves that models the number of times a random event occurs. This distribution is appropriate for applications that involve counting the number of times a random event occurs in a given amount of time, distance, area, and so on. Sample applications that involve Poisson distributions include ...
