Abstract :

In this paper, we investigate a nonparametric robust estimation for spatial regression. More precisely, given a strictly stationary random field $Z_{mathbf{i}}=(X_{mathbf{i}},Y_{mathbf{i}})$, $mathbf{i}inmathbb{N}^{ N}$, we consider a family of robust nonparametric estimators for a regression function based on the kernel method. We establish a $p$-mean consistency results of the kernel estimator under some conditions.
