Abstract:

This paper considers the estimation of partially linear varying-coefficient models, which are useful extensions of varying coefficient models and partially linear models. The author focuses on the case where some covariates are measured with additive errors and the response variable is sometime missing. A class of estimators for the parametric component as well as nonparametric components based on the profile least-squares approach are proposed. The first estimator is constructed by using complete-case observations only, the other two by using simple imputation or replacement techniques respectively to complete the sample. All the proposed estimators for the parametric component are shown to be asymptotically normal, and the estimators of nonparametric component achieve the optimal strong convergence rate of the usual nonparametric regression. For the mean of response variable, two estimators are constructed and their asymptotic normalities are established. Simulation studies are conducted to illustrate the approach.

Key words: Asymptotic normality, Measurement error, Missing data, Partially linear varying-coefficient model, Profile least-squares approach
