“…For the counting process with a general fat tail waiting time distribution (that has a power law decay as t → ∞), an existence of the affine part in the scaled cumulant generating function (sCGF) G(s) = lim t→∞ (1/t) ln E[e sNt ] has been proven [16]. When the sCGF is analytic, it can be expanded using scaled cumulants ci (i = 1, 2, ...) as G(s) = ∞ i=1 (c i /i!…”
