The Local Linear Two Stage Estimation for Semiparametric Spatially Varying-coefficient Regression Model

针对半参数空间变系数模型,利用二阶段估计方法借助于局部线性拟合技术给出了模型中常值系数估计量的精确表达式;同时给出了实验设计方法,用于验证所提出的估计方法对估计常值系数具有满意的精度和稳定性.

The local Unear two stage estimation for fitting the semipaxametric 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 axe conducted to examine the performance of the proposed fitting procedure and the results demonstrate that the estimators for the constant coefficients axe quite accurate and stable.
