Based on the results shown in Table 2, it is evident that the -estimator is much more robust than but suffers from leverage points.
Web1 de jan. de 1992 · In this paper we construct several new estimators of scale which attain a 50% breakdown point. We are looking for scale estimators which are explicit, robust, … WebIt has a high breakdown point and is very fast to compute. However, it is not computable in high dimensions. Another estimator with very nice theoretical properties is the affine equivariant rank covariance matrix (Ollila et al. 2003). It is very efficient and has maximal breakdown point.
WebEstimators with high finite sample breakdown points are of special interest in robust statistics. However, in contrast to estimation in linear regression models the breakdown … Web1 de jan. de 2012 · Equivariant high-breakdown point regression estimates are computationally expensive, and the corresponding algorithms become unfeasible for moderately large number of regressors. One important advance to improve the computational speed of one such estimator is the fast-LTS algorithm.
Web1 de jan. de 2012 · The computing times of high-breakdown point estimates of multivariate location and scatter increase rapidly with the number of variables, which makes them impractical for high-dimensional datasets, such as those used in data mining.
WebA breakdown point is the point after which an estimator becomes useless. It is a measure of robustness; The larger the breakdown point, the better the estimator. If an estimator has a high breakdown point, it may be called a resistant statistic.
