The mortality modeling and forecasting is of fundamental importance in many areas, such as funding of public and private pensions, life insurance, the care of the elderly or the provision of health services. The book is an attempt to approach this su

In this paper, a new approach to mortality forecasting is proposed based on an improved model of the Lee-Carter type. The standard Lee-Carter model and its modified version were introduced and compared using mortality data for Poland and some other E

The paper deals with a new fuzzy version of the Lee-Carter (LC) mortality model, in which mortality rates as well as parameters of the LC model are treated as triangular fuzzy numbers. As a starting point, the fuzzy Koissi-Shapiro (KS) approach is re

The forecasting of mortality is of fundamental importance in many areas, such as the funding of public and private pensions, the care of the elderly, and the provision of health service. The first studies on mortality models date back to the 19th cen

Mortality is generally considered relatively easy to forecast, particularly when the forecasting horizon is short. In longer periods however, its course may be affected by various changes brought about by all kinds of disturbances and events, A case

This article deals with some statistical properties of the modified Kaplan–Meier and Nelson–Aalen estimators defined for a right-censored sample under a certain sequential sampling scheme. Both types of estimators were proposed by Rossa in the ar

The paper deals with two classes of unbiased nonparametric estimators of survival and cumulative hazard functions in a population subject to right-censoring. Both classes of estimators are based on a sequential sampling scheme, and are similar to the
