  • Multidimensional outlier detection and robust estimation using Sn covariance 
    Kunjunni, Sajana O; Abraham, Sajesh T (Taylor & Francis Online, 2020-02-17)
    This article presents a robust method for detecting multiple outliers from multidimensional data using robust Mahalanobis distance. Initial scatter matrix for robust Mahalanobis distance is constructed using a robust ...
  • Sn covariance 
    Kunjunni, Sajana O; Abraham, Sajesh T (Taylor & Francis Online, 2019-06-16)
    Main purpose of this paper is to study a robust measure of estimating dependence between random variables that can be used as an alternative to classical covariance estimator. An efficient univariate nested L-estimator ...
