Ridge Estimation Method for Ill-Conditioned Semiparametric Regression Model

LIU Yun-hang,SONG Li-jie(Institute of Surveying and Mapping,Information Engineering University,Zhengzhou,Henan,450052)  
This paper uses ridge estimation method to solve the potential ill-conditioned problem in semiparametric regression model.Then,a simulated adjustment problem is used to explain the method.The results of the ridge estimation method and nomal semiparametric regression model are compared,which demonstrates that the ridge estimation method can solve the ill-conditioned semiparametric regression problem well.
