二项分布、泊松分布、正态分布的关系及比较内容摘要概率论中最基本的概率分布是二项分布、泊松分布以及正态分布这三种随机变量的分布,并且这三种分布也是生活中最常用的分布方式,这三种分布方式在一定的条件下,有着非常密切的联系,本文给出了这几种概率分布之间通过极限关系达成的近似,运用到了特征函数、分布函数、极限分布等知识,并根据三种分布之间的关系举出例子,便于更好地理解这三种概率分布
【关键词】二项分布 泊松分布 正态分布 极限The relation and comparison of binomial distribution, Poisson distribution and normal distribution AbstractProbability theory is the most basic probability distribution in the binomial distribution, Poisson distribution and normal distribution of the three, the distribution of random variables and distribution of the three distribution is the most commonly used in life, one of the three distribution under certain conditions, has a very close connection, the several kinds of probability distribution are given in this paper through the ultimate relationship between approximate, using
