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.
