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。
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.
