摘要
在测量数据处理中 ,为了克服粗差对数据分析的影响 ,采用的办法之一是定位 ,删去粗差 .通过小波多分辨分析方法对测量数据进行处理 ,可有效地发现和定位其中的粗差 ,并举一半参数模型的例子加以说明 .
In data processing,in order to overcome influence of the gross-error data on data analyzing,one of methods is location and cancellation it.In this paper,after the data measured are processed by the method of wavelet multiresolution analysis,the gross-error data are detected and located.The method avoids some deficiencies of some methods,Which already have obtained.At last,inorder to demonstrate the method of validity,one example about semiparametric regression model is given.
