Outlier Detection in Regression Using an Iterated One-Step Approximation to the Huber-Skip Estimator

open access: yesEconometrics, 2013
In regression we can delete outliers based upon a preliminary estimator and re-estimate the parameters by least squares based upon the retained observations. We study the properties of an iteratively defined sequence of estimators based on this idea.

A Parameterization of Models for Unit Root Processes: Structure Theory and Hypothesis Testing

open access: yesEconometrics, 2020
We develop and discuss a parameterization of vector autoregressive moving average processes with arbitrary unit roots and (co)integration orders. The detailed analysis of the topological properties of the parameterization—based on the state space ...
