摘要

针对外弹道测量数据质量情况,拓展数据质量评价标准,提出了用分布偏度与峰度的分析方法描述数据质量状态。通过对跟踪测量数据进行分析验证,证明运用该方法可有效、直观的定量、定性的确定数据质量情况,为跟踪测量数据的使用提供了可靠性评价及使用决策。

Abstract

Due to quality of trajectory measurement data and extension of quality standard, distributed skewness and kurtosis analysis were put forward. It is proved that application of the method is able to determine quantitative and qualitative quality of data effectively and directly by analysis and verification of measurement data. Also, the method provides reliability evaluation and suggestion on measurement data.

Key words： skewness; kurtosis; data analysis; assessment of results
