This short paper provides tutorial guidance in the use of the R files within the Github repository affine_mortality containing the code used to fit, examine and compare continuous-time affine mortality models. The final implementation will be available as the R package AffineMortality....

Affine mortality models, developed in continuous time, are well suited to longevity applications including pricing and risk management. Advantages of this modelling approach include closed-form derivations of cohort survival curves, with these survival curves consistent with the dynamics of...

In this paper, we investigate the dynamics of age-cohort survival curves under the assumption that the instantaneous mortality intensity is driven by an affine jump-diffusion (AJD) process. Advantages of an AJD specification of mortality dynamics include the availability of closed-form...
