The bias of k-step M-estimators

Peter Rousseeuw () and Christophe Croux

Statistics & Probability Letters, 1994, vol. 20, issue 5, 411-420

Abstract: It is well-known that k-step M-estimators can yield a high efficiency without losing the breakdown point of the initial estimator. In this note we derive their bias curves. In the location framework the bias increases only slightly with k, but in the scale case the bias curves change considerably.
