Further, we prove that the Dirichlet-type characteristic function is infinitely divisible if the coefficient (as an arithmetical function) in the Dirichlet series is completely multiplicative. By way of applications, in Section 3 we shall give the prob- Web1 The Dirichlet distribution The Dirichlet distribution is a model of how proportions vary. Let pdenote a random vector whose elements sum to 1, so that pk represents the proportion of item k. Under the Dirichlet model with parameter vector α, the probability density at pis p(p) ∼ D(α 1,...,αK) = Γ(P Q k αk) k Γ(αk) Y k pαk−1 k (1 ...
