摘要
针对靶场外测数据中存在的"隐蔽性"野值难以发现和剔除的问题,本文采用一阶差分法对其加以识别,并基于M-型估计理论和拉格朗日条件极值原理,提出了一种能识别和修复这种野值的新方法,通过对测量数据进行Matlab仿真分析处理,验证了该方法的实用性和高效性。
To solve the question of hard to find and eliminate the‘ covert＇ outliers in data processing, this paper adopts a method of one order difference, and brings forward a new method to detect and correct depply-covered patch-type outliers which is based on M-estimation theory and Lagrange formula condition extremum. By analyzing and processing the measurements with Matlab emulation, the practicability and efficency of this method are verified.
