Multi-population mortality modelling: a Bayesian hierarchical approach (Q6494322)

Authors in this paper do cope with modelling of joint population mortality models. The significance of such a model is the obvious motivation for the paper, since life insurance branch is always a question of risk management. The components of the joint time -series, which are tested are logarithmic. This fact provides a flexibility in handling, since the time-series is jointly `linearized'. An interesting point of the paper is that estimations of the parameters are proved to be coherent.
