The calculation of exact confidence limits for the expectation value of a Poisson distribution when a single observation of K events is given by means of a second order iterative algorithm was recently presented. Here it is shown that the structure of the equations to be solved admits the use of a third order algorithm, thereby significantly reducing computation time, especially for pocket calculators, with practically no additional computational effort.
最近提出了一种二阶迭代算法，用于在给出K个事件的单次观测值时计算泊松分布期望值的精确置信限。本文表明，待求解方程的结构允许使用三阶算法，从而显著减少计算时间，特别是对于袖珍计算器而言，几乎无需额外的计算量。
