改进二项分布的性质及其应用
Improved Binomial Distribution Model and Its Properties
摘要
Abstract
Probability of binomial distribution is a broad use of discrete distribution of random variables. Aiming at the limitations for application of the binomial distribution, an improved model is proposed ,which is based on binomial distribution. The scope of binomial distribution is expanded by introducing the control parameters, which makes the processed data source meet the binomial distribution characteristics as well as their own relevant characteristics of the data sets. Finally ,the values of the parameters are obtained by constructing the moment equation or the maximum likelihood parameter estimation equation.关键词
