Abstract : In this talk, we consider the lack-of-fit test for linear spatial autoregressive models with high-dimensional covariates. Combining the unidimensional linear projections of the covariates with the residual marked empirical process, a projection-based test procedure is proposed. Under mild conditions, we establish the consistent of the proposed test statistic, and show that the proposed test can detect Pitman local alternatives converging to the null at the usual parametric rate. To obtain the finite sample properties of the proposed test, we develop a wild bootstrap method to obtain the p-value, and show the validity of the proposed bootstrap method. Some Monte Carlo are implemented to investigate the finite sample performance of our new procedure, and show that the proposed test method produces satisfactory results. Finally, the developed methodology is illustrated by two real data examples.
