Flexible Class of Skew-Symmetric Distributions
Authors:Yanyuan Ma  Marc G Genton
Institution:North Carolina State University
Abstract:Abstract.  We propose a flexible class of skew-symmetric distributions for which the probability density function has the form of a product of a symmetric density and a skewing function. By constructing an enumerable dense subset of skewing functions on a compact set, we are able to consider a family of distributions, which can capture skewness, heavy tails and multimodality systematically. We present three illustrative examples for the fibreglass data, the simulated data from a mixture of two normal distributions and the Swiss bills data.
Keywords:dense subset  generalized skew-elliptical  multimodality  skewness  skew-normal
