AB An iteratively reweighted approach for robust clustering is presented inthis work. The method is initialized with a very robust clustering partitionbased on an high trimming level. The initial partition is then refinedto reduce the number of wrongly discarded observations and substantiallyincrease efficiency. Simulation studies and real data examples indicate thatthe final clustering solution is both robust and efficient, and naturally adaptsto the true underlying contamination level.
