Robust Estimation in Semiparametric Regression Model

HU Hong chang (Departmant of Mathematics,Hubei Normal University,Hubei Huangshi 435002; School of Geodesy and Geomatics,Wuhan University,Hubei Wuhan 430079)  
In this paper,Consider the semiparametric regression model y i=X T iβ+g(t i)-ε i for i=1,2,...,n The first,β∧ and g∧(t) are derived by using the principle of robust estimation.Then the estimators of the covariance matrix,based on influence function,are derived.
