| Abstract: | In this paper we provide an interval of existence of mortality rate parameters A and α, and their asymptotic expressions in a Gompertz survival model with mortality deceleration rate, in the absence of age specific mortality data. |
| Keywords: | Asymptotic formulae Deceleration rate Gompertz parameter Logistic frailty model Maximum lifespan Mortality rate Survival function |
