WebAn appropriate two-population model was built for EW male lives and CMI assured male lives to measure longevity basis risk, and the relative approach to model the populations was adopted. The modelling process of the reference population was followed by the modelling of the dynamics of the book population’s mortality. A population model is a type of mathematical model that is applied to the study of population dynamics.
