Web1 Answer. Let KX(t) = log(E(etX)) the cumulant generating function of X ∼ IG(μ, λ). using the identity K1 2(z) = (π 2z)1 2e − z, z > 0. Thus we have KX(t) = λ μ + log(e − β) = λ μ − [2λ2( 1 2μ2 − t λ)]1 2 and finally KX(t) = λ μ[1 − (1 − 2μ2t λ)1 2]. Observing that if X ∼ IG(μ, λ), then X n ∼ IG(μ n, λ n ...
