| Abstract: | The local linear two stage estimation for fitting the semiparametric spatially varying-coefficient regression model is proposed,by which an explicit expression for estimators of the constant coefficients in the model can be obtained.Experimental design method are conducted to examine the performance of the proposed fitting procedure and the results demonstrate that the estimators for the constant coefficients are quite accurate and stable. |
