Web1 de jan. de 2003 · This estimator has the highest breakdown point, namely 50 per cent. This implies that nearly one-half of the data can be outliers, but the solution will still yield a reasonable result. However, methods with a very high breakdown point usually have a smaller asymptotic relative efficiency at the Gaussian distribution than LS.
