Abstract

We study the Tweedie family distributions as special cases of exponential dispersion models (EDMs) which are two-parameter distributions from the exponen- tial family that have a scale parameter λ. According to such parameterization, the mean and variance for the Tweedie random variable X are given by E(X) =Γµ and Var(Y)= λµ , respectively, where p is an extra parameter that controls the variance of the distribution which is called “variance power” parameter. From this perspective, p some properties of Tweedie distribution are discussed. The multivariate extensions of Tweedie family are also presented.
