Affine Equivariant Rank-Weighted L-Estimation of Multivariate Location

  • Chapter
Book cover Modern Nonparametric, Robust and Multivariate Methods

Abstract

In the multivariate one-sample location model, only L-estimators are affine equivariant; we propose a class of flexible robust, affine equivariant L-estimators of location, for distributions invoking affine-invariance of Mahalanobis distances of individual observations. An involved iteration process for their computation is numerically illustrated.
