Locate Gross-Error Data by Means of Wavelet Analysis
Cheng Wenjing · Journal of Hubei Institute for Nationalities · 2002
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.
