摘要: 为在小样本情况下进行弹道一致性的评定,基于正态分布小样本相容性理论给出一种弹道一致性评定方法。该方法主要通过将计算的顺序统计量与计算机模拟的临界值进行比较判定。主要优点是不需计算位置-尺度估计值,从而减小由于样本容量小而带来的计算误差。通过算例分析表明:在样本数量较少(n≤5)的情况下,该方法与常规的配对t检验法和概率圆序贯检验法相比,都具有一定的优势。

Abstract: In order to evaluate ballistic consistency under small sample circumstance, an evaluation method of ballistic consistency is proposed based on the normal distribution small sample compatibility theory. This method is to compare the calculated order statistics and the simulated critical value to determine the ballistic consistency. The main advantage is not necessary to calculate the position- scale estimate value, so it could decrease the calculation error due to small sample size. The calculation shows that this method is better than matched pair t test and probability circle sequential test under small sample circumstance (n≤5).
