Gómez Villegas, Miguel Ángel and Gómez Sánchez-Manzano, Eusebio and Marín Diazaraque, Juan Miguel (2008) Multivariate exponential power distributions as mixtures of normal distributions with Bayesian applications. Communications in statistics. Theory and methods, 37 (6). pp. 972-985. ISSN 0361-0926
It is shown that a multivariate exponential power distribution is a scale mixture of normal distributions, with respect to a probability distribution function, when its kurtosis parameter belongs to the interval (0,1]. The corresponding mixing probability distribution function is presented. This result is used to design a Bayesian hierarchical model and an algorithm to generate samples of the posterior distribution; these are applied to a problem of Quantitative Genetics.
