The models just described are in the reproductive form. An exponential dispersion model has always a dual: the additive form. If Y is reproductive, then with is in the additive form ED (θ,λ), for Tweedie Tw p(μ, λ). Additive models have the property that the distribution of the sum of independent random variables, for which Zi ~ ED (θ,λi) with fixed θ and various λ are members of the family of distributions wit… Web1. However, in general a Tweedie distribution with an index parameter equal to one may not be referring to a Poisson distribution with ˚= 1, so we cannot assume that ˚= 1 just because the index parameter is set to one. If the Poisson distribution is intended, then dispersion=1 should be specified. The same argument applies for similar ...
