THE STUDY ON THE ROBUSTNESS OF L_p ESTIMATION

Zhou Shijian;Chen Yongqi(Wuhan Technical University of Surveying and Mapping)  
Abstract In this paper,the basic principles are discussed of L_p estimation. Based on the robustnessmeasure targets of influence function and the basis distribution of the data is the normal dis-tribution , the robustness and efficiency of L_p estimatico are discussed and analysed in detail.We can obtain the relation between the robustness or efficiency of L_p estimation and the pa-rameter p. Key words L_p estimation,Robustness,Efficiency,Influence function
