效率计算中的误差处理
Treatment of Errors in Efficiency Calculations
摘要：
在这份报告中，我们讨论的处理统计误差的削减效率。两种常用的方法计算的错误，泊松和二项式，是有缺陷的。我们推导出基本的概率密度函数的形式，并描述其平均值，模式和方差。讨论了一种基于分布方差的误差计算方法。
英文摘要：
In this report we discuss the treatment of statistical errors in cut efficiencies. The two commonly used methods for the calculation of the errors, Poissonian and Binomial, are shown to be defective. We derive the form of the underlying probability density function and characterize its mean, mode, and variance. A method for the calculation of errors based on the variance of the distribution is discussed.
