A Method of Ridge Estimation Parameters Determining

WANG Jian-qiang1,XING Cheng1,ZHU Guang-bin1,JIA Zhi-qiang2(1.School of Geodesy and Geomatics,Wuhan University,Wuhan Hubei 430079,China;2.Tianjin Institute of Geotechnical Investigation & Surveying,Tianjin 300191,China)  
Based on least square estimation,ridge estimation is an estimated decrease of the mean square error method biased estimate and it lies on the determination of estimation parameter.According to the characteristics of computer data storage that the large numbers and the small numbers are power function,this paper proposes a method that how to determine the Ridge parameters with the chosen of determinant of the normal equation coefficient matrix,and the example verifies the feasibility of this approach.
