Gompertz-Makeham Life Expectancies:Analytical Solutions, Approximations, and Inferences

2012
We study the Gompertz and Gompertz-Makeham mortality models. We prove that the resulting life expectancy can be expressed in terms of a hypergeometric function if the population is heterogeneous with gamma-distributed individual frailty, or an incomplete gamma function if the study population is homogeneous.
