Triply noncentral bivariate beta type V distribution

Abstract

The enriched triply noncentral bivariate beta type V distribution is introduced. This distribution is constructed from independent chi-squared random variables by using the variables-in-common (or trivariate reduction) technique. The marginal density, product moment and the distribution of the product of the correlated components of this distribution are also derived. The effect of the additional parameters on the shape of the density functions and the correlation between the correlated variables is shown. Special cases are highlighted to position this distribution in the bivariate beta distributions context.
