Web31 de ago. de 2024 · High-breakdown-point estimators of multivariate location and shape matrices, such as the MM-estimator with smooth hard rejection and the Rocke S-estimator, are generally designed to have high efficiency at the Gaussian distribution.However, many phenomena are non-Gaussian, and these estimators can therefore have poor efficiency. … 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.
