多维超几何分布的概率计算问题研究

Study on the Problem of Probability Calculation of Multidimensional Hyper Geometric Distribution

把超几何分布进行了推广,引出多维超几何分布的定义,给出了多维超几何分布最可能成功数.并在此基础上,探讨了多维超几何分布、多项分布和多维Poission分布之间的极限分布,从而可以解决超几何分布的概率计算问题.

In this paper, the hyper geometric distribution is generalized, and the definition of multidimensional hyper geometric distribution is drawn out, and the most probable success number of multidimensional hyper geometric distribution is given. And on the basis of this, the limit distribution of multidimensional hyper geometric distribution, muhinomial distribution and multidimensional Poission distribution are discussed, which can solve the problem of the proba- bility calculation of the hyper geometric distribution.
