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. … Web1 de jan. de 2014 · For example, the high breakdown point S-estimators of regression even lack the crucial stability attribute of robust procedures (Davies 1993, Section 1.6). With high values of ε, alternative interpretations of contamination models become important, transcending the ubiquitous presence of a small fraction of gross errors.

High breakdown point

Websufficiently robust to a substantial amount of outliers, i.e. whether they have high breakdown points. The breakdown point, ?*, is the smallest fraction of outliers that can cause an estimator to take on arbitrarily values. Loosely speaking, a robust estimator is one with a high breakdown point. Donoho & Huber (1983) pointed out that an estimator 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.
