广义 x^2分布下检验导弹精度的序贯法

THE SEQUENTIAL METHOD CHECKING MISSILE ACCURACY UNDER THE GENERALIZED CHI-SQUARED DISTRIBUTION

本文利用 Grubbs 的广义 x^2分布,讨论了在标准偏差比 v=τ/σ未知的情况下检验导弹精度的序贯法。提出序贯界限 A、B 新的取值,并讨论了这种取值对检验所犯两类错误概率的影响以及检验的 OC 函数的样本期望值。最后通过计算,与 Haggstrom 提出的方法进行了比较。

By using Grubbs generalized Chi-squared distribution [1],we discuss thesequential method checking missile accuracy without the knowledge of the standard deviationratio v=τ/σ in this paper.The new boundaries A,B are put forward,which influence on theerror probabilities associated with the new boundaries is researched and compared with thehaggstroms' results[2] by computing.And then,properies for the OC function and the ex-pected sample size E_θ(n) are discussed.
