Shape mixtures of multivariate skew-normal distributions

Abstract: a b s t r a c tClasses of shape mixtures of independent and dependent multivariate skew-normal distributions are considered and some of their main properties are studied. If interpreted from a Bayesian point of view, the results obtained in this paper bring tractability to the problem of inference for the shape parameter, that is, the posterior distribution can be written in analytic form. Robust inference for location and scale parameters is also obtained under particular conditions.

“…The issue is that our greedy extraction of polynomial limits for the system (65) treats each equation of the system separately. For instance, in system (67), a special case of system (65) when r = 3, we do not consider the interaction between two summations 3 in the numerator of the second limit. As a result, the limiting polynomials obtained are dependent only on the lowest order monomial terms that appear in the numerator of each of the (r, r, r)-minimal form's coefficients.…”

“…The idea of shape mixture of a skew-symmetric distributions is introduced by Arellano- , (see also Arellano-Valle et al (2009)) and is applied by Arrue et al (2011) to the univariate SNC distribution. Following Genton and Loperfido (2005), the multivariate SNC distribution is defined as follows.…”
