A calculator for confidence intervals

Abstract A calculator program has been written to give confidence intervals on branching ratios for rare decay modes (or similar quantities) calculated from the number of events observed, the acceptance factor, the background estimate and the associated errors. Results from different experiments (or different channels from the same experiment) can be combined. The calculator is available in http://www.slac.stanford.edu/~barlow/limits.html. Title of program: syslimit Catalogue Id: ADQN_v1_0 Nature of problem Calculating confidence intervals for a Poisson mean based on observed data, with uncertainties in efficiencies and backgrounds. Versions of this program held in the CPC repository in Mendeley Data ADQN_v1_0; syslimit; 10.1016/S0010-4655(02)00588-X This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)摘要 本程序开发了一套计算工具，可基于观测事件数、接收因子（acceptance factor）、本底估计值及其相关误差，为稀有衰变模式（rare decay modes）的分支比（branching ratios）或同类物理量计算置信区间（confidence intervals）。可整合不同实验（或同一实验的不同探测道）的结果。该程序可通过http://www.slac.stanford.edu/~barlow/limits.html获取。 程序名称：syslimit 目录编号：ADQN_v1_0 问题特性 基于观测数据计算泊松均值（Poisson mean）的置信区间，同时考虑效率与本底的不确定性。 本程序在Mendeley数据（Mendeley Data）库的CPC程序库中的版本信息为：ADQN_v1_0；syslimit；10.1016/S0010-4655(02)00588-X 本程序源自贝尔法斯特女王大学托管的CPC程序库（1969-2019年）
