Robustness of Time Series Forecasting Based on Regression Models, the .-admissible distortion level. Robust forecasting statistics are constructed by using Huber estimators and a specially chosen type of M-estimators for the regression function parameters. A local-median forecasting algorithm is proposed to mitigate the influence of outliers under regression models, and its robustness is evaluated.

Optimality and Robustness of ARIMA Forecasting,lgorithms is evaluated under the following distortion types: parametric model specification errors, functional distortions of the innovation process in the mean value, heteroscedasticity, AO and IO outliers, bilinear autoregression distortions.

Optimality and Robustness of Vector Autoregression Forecasting Under Missing Values,nd model specification errors. In the case of parametric prior uncertainty, a consistent forecasting statistic and an asymptotic expansion of the corresponding forecast risk are obtained. The chapter is concluded by considering plug-in forecasting under simultaneous influence of outliers and missing values.
