    Phase-Type Distribution Approximations of the Waiting Time Until Coordinated Mutations Get Fixed in a Population

    In this paper we study the waiting time until a number of coordinated mutations occur in a population that reproduces according to a continuous time Markov process of Moran type. It is assumed that any individ...

    Continuous Approximations of Discrete Choice Models Using Point Process Theory

    We analyze continuous approximations of discrete choice models with a large number of options. We start with a discrete choice model where agents choose between different options, and where each option is defi...

    Nonlinearly Perturbed Birth-Death-Type Models

    Asymptotic expansions are presented for stationary and conditional quasi-stationary distributions of nonlinearly perturbed birth-death-type semi-Markov models, as well as for computing coefficients of ...
