摘要
本文给出了生产实践中被广泛应用的负二项分布的五种定义,研究了该分布对应随机变量的期望、方差等数字特征的求解,汇总了负二项分布与其它分布之间的关系.
This paper presents five definitions of negative practice, and studies their numerical characteristics such summarizes the relationship between the negative binomial binomial distributions, which is widely used in as expectation, variance, etc. This paper also distribution and other distributions.
