A note on the direction maximizing skewness in multivariate skew-t vectors

  • Navarro, Hilario

Abstract

In this note we address the problem of finding the direction with maximal skewness for a random vector that follows a multivariate skew-t distribution. The result relies on the well-known representation of the multivariate skew-t distribution as a scale mixture of skew-normal multivariate distributions.
