Estimating Tail Probabilities of Random Sums of Phase-Type Scale Mixture Random Variables

open access: yes, 2022
We consider the problem of estimating tail probabilities of random sums of scale mixture of phase-type distributions—a class of distributions corresponding to random variables which can be represented as a product of a non-negative but otherwise ...
