Nonparametric Bootstrap Method for Missile Precision Evaluation

Based on the actual circumstance of missile experiments at the present time, this paper discusses nonparametric Bootstrap method used for confidence interval estimation of precision indices in small sample case. Following introduction of the basic concept of Bootstrap method, the characteristics of nonparametric Bootstrap sampling and parametric Bootstrap sampling are compared. Then, the improved confidence interval estimation methods based on traditional percentile method, including iterative Bootstrap method and Bootstrap-t method and corrected percentile method, are briefly summarized. Finally, the performance and applicable range of various nonparametric Bootstrap confidence interval estimation methods are analyzed through a repeated simulation, and some beneficial engineering suggestions are given.
