摘要
给出了射弹落点样本变异系数的概率密度函数,分析了变异系数的分布规律,建立了计算样本变异系数概率分位数的模拟方法.提出了针对不同的变异系数指标的检验方法,给出了存伪概率、弃真概率的计算方法,对武器的研制与试验具有指导作用.
The sample variability coefficients and population variability coefficients of the falling points of projectiles were defined. The distribution characteristics of variability coefficients were analyzed. The density function of the sample variability coefficient being a random variable was obtained. For different indexes of variability coefficients, the different testing methods were presented. The calculation methods of the probability of Type Ⅰ error and Type Ⅱ error were given. This is helpful to the study on armament systems.
