远程火炮密集度试验多组数据的处理方法

Data Processing Method for Multiple Sets of Data from Dispersion Test of Long-range Artillery

远程火炮密集度试验需要进行多次射击,同一试验条件下的多组数据通常认为来源于同一分布,但却未见于证明。利用统计检验方法,给出了对试验数据方差齐性及均值相等性的检验方法,并在多组试验数据一致性的基础上给出了试验数据均值、方差的无偏估计,同时在既定置信度下给出了其置信区间,为远程火炮精度检测提供了工具。

In the dispersion test of long-range artillery,several sets of testing data are need. It is generally considered that the sets of data follow to an identical normal distribution because of the same testing environment,which has not been proved. Based on this situation,this paper shows how to testify homogeneity of variance and equality of mean with the help of statistical test method. After that,the unbiased estimations of mean and variance are given on the assumption of consistency,and meanwhile the confidence intervals at the certain confidence level are specified,thus providing method for accuracy test of long-range artillery.
