标准摘要
[中文适用范围]： 本文件提出了确定泊松分布测量中响应变量临界值和最小可检测值的方法。它适用于背景噪声和信号的变化均可用泊松分布描述的情况。根据ISO 11843-3和ISO 11843-4，使用常规近似法通过正态分布来近似泊松分布。与精确泊松分布相比，正态近似的准确性在附录B中讨论。 [外文原描述]： This document presents methods for determining the critical value of the response variable and the minimum detectable value in Poisson distribution measurements. It is applicable when variations in both the background noise and the signal are describable by the Poisson distribution. The conventional approximation is used to approximate the Poisson distribution by the normal distribution consistent with ISO 11843-3 and ISO 11843-4. The accuracy of the normal approximation as compared to the exact Poisson distribution is discussed in Annex B.
