Nejpoužívanější metody vyrovnávání a extrapolace křivky úmrtnosti a jejich aplikace na českou populaci

Abstract

Demographers have constantly tried to find a way of modelling the relationship between mortality and age. So far the Gompertz-Makeham function was for a long time universally used and considered sufficient. As a result of improving oldest-old mortality and better statistical data many new models have emerged that try to illustrate better the development of mortality with age. In this article, some of those models are introduced and fitted to Czech mortality data. Based on the results it is possible to specify three groups of models. The Gompertz-Makeham function belongs to the most pessimistic one, leading to the underestimation of the probabilities of survival and life expectancy
