Spatial Sign Correlation (1403.7635v1)
Published 29 Mar 2014 in stat.ME
Abstract: A new robust correlation estimator based on the spatial sign covariance matrix (SSCM) is proposed. We derive its asymptotic distribution and influence function at elliptical distributions. Finite sample and robustness properties are studied and compared to other robust correlation estimators by means of numerical simulations.
