Multivariate Skew Normal Copula for Asymmetric Dependence: Estimation and Application

Abstract: The exchangeability and radial symmetry assumptions on the dependence structure of the multivariate data are restrictive in practical situations where the variables of interest are not likely to be associated to each other in an identical manner. In this paper, we propose a flexible class of multivariate skew normal copulas to model high-dimensional asymmetric dependence patterns. The proposed copulas have two sets of parameters capturing asymmetric dependence, one for association between the variables and the… Show more

“…Since the copula functions have flexibility to reflect the non-linear relationships between variables, so constructing an asymmetric distribution from nonlinear dependent variable would be of interest. Moreover, the approach of this work can be extended for modeling high-dimensional asymmetric dependence patterns, see, e.g., Wei, Kim, Choi, and Kim (2019); Kurowicka and Cooke (2006). Finally, it is well known that the asymetric distributions are frequently used as an approach to model the behavior of order statistics, see e.g., Loperfido (2008) and Sheikhi and Tata (2013).…”

“…Wu et al (2014) uses a nonparametric Bayesian approach to construct infinite mixture skew normal copula. Wei et al (2019) explored some theoretical properties of the skew normal copula. Alternatively, Archimedean families of copulas are another solution for the issue.…”

“…Instead, we may extract Kendall's tau coefficient from the copula functions to compare correlations. Kendall's tau coefficient is measured by the difference between the probability of concordance and the probability of discordance of two pairs of random variables [42]. The Kendall's tau (τ) for the random vector (X, Y) T is defined as…”
