计算负超几何概率分布的迭代算法

An Iterative Algorithm of Calculating Probability Mass Function for Negative Hypergeometric Distribution

当负超几何分布的中参数变大时,为克服计算其概率分布律时需要计算大阶乘而产生的计算机上溢问题,给出计算概率分布律的简便迭代公式和计算机程序,通过数值分析和比较,验证了递推公式和程序的正确性.

To address the issue of computer overflow resulting from the evaluation of large factorials,this paper presents a straightforward iterative formula and computer program for calculating the probability mass function of the negative hypergeometric distribution.The correctness of both the formula and program is validated through numerical analysis and comparison.
