The methods of very robust regression resist up to 50% of outl iers. The algorithms for very robust regression rely on selecting numerous subsa mples of the data. We describe new algorithms for LMS and LTS estimators that have in creased efficiency due to improved combinatorial sampling. These and other public ly available algorithms are compared for outlier detection. An algorithm using the f orward search has the best properties for both size and power of the outlier tests.
