摘要:In this talk, we consider a specification test for partially linear quantile regression models with high-dimensional covariates, which combines basis function approximations and unidimensional linear projections of the covariates. Under mild conditions, we establish the consistency of the proposed test method, and show that the proposed test can detect Pitman local alternatives converging to the null at the usual parametric rate. To improve the finite sample properties of the proposed test, we develop a wild bootstrap method to obtain the critical values or p-values, and show the validity of the proposed bootstrap method. We conduct Monte Carlo studies to investigate the finite sample performance

of our new procedure, and find that the proposed test method produces

satisfactory results. Finally, the proposed test method is illustrated by two real data examples.
