摘要
考虑离散事件仿真中一个非平均性能测度——比例的估计问题．在对有关比例的已有估计方法的概述和分析的基础上，提出了一种比例的Ｂａｙｅｓ估计方法和贝塔分布的区间估计方法．从实验上对这些方法进行了研究和比较，从而证明了Ｂｅｙｅｓ方法能合理地给出比例的估计，而且仿真精度在大样本情形比已有方法略有提高。
Based on the reviewing and analyzing the previous estimation method of proportion from simulation outputs in the literature, a Bayesian estimation method of proportion and an estimation method of confidence intervals about a beta distribution are proposed. All these methods are investigated and compared experimentally.Furthermore it is clarified that the Bayesian method can give the estimates of proportion reasonably and improve the simulation precision,especially the effect is more obvious in small samples.
