WebThe Annals of Statistics. We propose an affine equivariant estimator of multivariate location that combines a high breakdown point and a bounded influence function with high asymptotic efficiency. 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.

WebThese estimates, called MM-estimates, have simultaneously the following properties: (i) they are highly efficient when the errors have a normal distribution and (ii) their breakdown … Webcases, they have an improved ﬁnite-sample breakdown point of 1/(p+1). The repeated median estimator [Siegel (1982)] with breakdown point of approximately 50%, was one of the earliest estimators to achieve a very high breakdown point. The estimator however, is not equivariant under linear transformations of the covariates.
