• Multivariate normal stable Tweedie models are recently introduced as an extension to normal gamma and normal inverse Gaussian models. The aim of this paper is to characterize these models through their variance functions. Then, according to the power variance parameter values, the nature of polynomials associated with these models is deduced.
