Abstract

A conditionally contaminated linear model y = x T ß+z is considered where the errors z may have different contaminated normal distributions for different experimental conditions x. At this model one-step M-estimators have an asymptotic bias which should be bounded for robust estimators. For designs which have a support of linearly independent regressors, an algorithm for the calculation of one-step M-estimators which minimize the asymptotic mean squared error (MSE) is presented. The results of this algorithm are given for quadratic regression and for a problem in a one-way lay-out model.
