Web为了生成二项分布随机数, 可以生成 \(n\) 个两点分布随机数(长度为 \(n\) 的独立试验序列), 其和为一个二项分布随机数, 依次从独立试验序列中每 \(n\) 个求和就可以得到二项分布随机数序列。 这样的算法效率较差。 设法用定理6.2构造二项分布随机数。 二项分布取值概率有如下递推式: \[ p_{k+1 ... WebGenerating Gaussian Random Numbers. This note is about the topic of generating Gaussian pseudo-random numbers given a source of uniform pseudo-random numbers.
