Abstract

Tiku-Suresh modified maximum likelihood estimators necessitate the assumption of a particular distribution. New forms of the estimators which, like Huber M-estimators, only assume that the distribution is long-tailed symmetric (unspecified) are given. They have high breakdown and, through Simulations, are shown to be overall more efficient than M-estimators. (c) 2009 Elsevier B.V. All rights reserved.
