| 摘 要： | 根据武器系统精度是在一定空间上弹着点与瞄准点或平均弹着点之间距离的中位数的统计意义,在不对总体分布进行任何假设情况下,采用Bootstrap方法获得再生样本的中位数;利用非参数核密度估计方法确定中位数的分布密度函数;从而获得武器系统精度的分布特性。确定了考虑Bootstrap方法估计稳定性时所需的子样数。

| Abstract: | The accuracy of weapon system is median of the range which is between the point of impact and the aim point(or the mean point of impact) in certain space.From this point,by using Bootstrap method and nonparametric kernel density estimation,the median of regenerating samples,its density function and the distribution characteristic of the weapon system accuracy without the assumption of population distribution were obtained.The tested sample number was decided for the stability of estimation by Bootstrap meth... |
