Local M-estimator for nonparametric time series


  • Cai, Zongwu
  • Ould-Saïd, Elias


In this article, we investigate a robust version of local linear regression smoothers for stationary time series sequence by using robust-type local polynomial techniques. Under some regularity conditions, we establish the weak and strong consistency as well as the asymptotic normality of the proposed estimators.
