The centred parametrization for the multivariate skew-normal distribution

Abstract
For statistical inference connected to the scalar skew-normal distribution, it is known that the so-called centred parametrization provides a more convenient parametrization than the one commonly employed for writing the density function. We extend the definition of the centred parametrization to the multivariate case, and study the corresponding information matrix. (C) 2008 Elsevier Inc. All rights reserved.
