概率分布的方差
variance of a probability distribution
- 摘要本文介绍如何运用概率母函数来求超几何分布的期望和方差。
This article tells us how to use probability generating function to find the expectation and variance of super geometry distribution. - 本文提出了一个离散型概率分布:指数差分布,推导了该分布的最可能成功次数、数学期望和方差,探讨了该分布与几何分布的关系,给出了该分布在马尔可夫链模型中的应用。
A discrete probability distribution named as distribution of exponential difference is presented in this paper,formula to calculate the most probable success number,mathematical expectation and Variance are derived for this distribution,relationship between this distribution and geometric distribution is discussed,a application of this distribution in Markovian chain is given. - 摘要本文提出了一个离散型概率分布：指数差分布，推导了该分布的最可能成功次数、数学期望和方差，探讨了该分布与几何分布的关系，给出了该分布在马尔可夫链模型中的应用。
