In this note I show that the method proposed in Thomakos (2008) for optimal linear filtering, smoothing and trend extraction for a unit root process can be applied with no changes when a drift parameter is added to the process. The method in the aforementioned paper is based on Singular Spectrum...

Robust M–estimation uses loss functions, such as least absolute deviation (LAD), quantile loss and Huber’s loss, to construct its objective function, in order to for example eschew the impact of outliers, whereas the difficulty in analysing the resultant estimators rests on the nonsmoothness...

Unit root tests and cointegration tests are sensitive to atypical events as outliers and structural breaks. This paper … uses outlier robust estimation techniques to reduce the impact of these events on cointegration analysis. As a byproduct of … that OLS based cointegration can yield spurious cointegration …

This paper shows that the integrated modified OLS (IM-OLS) estimator developed for cointegrating linear regressions in Vogelsang and Wagner (2014a) can be straightforwardly extended to cointegrating multivariate polynomial regressions. These are regression models that include as explanatory...
