Modelo Lee-Carter extendido

open access: yesRect@, 2007
Aunque en la literatura actuarial el conocimiento de la evolución de la mortalidad se remonta a las primeras décadas del siglo XX, solo recientemente los cálculos actuariales han utilizado las tablas de mortalidad proyectadas o dinámicas. En consecuencia,

A Fuzzy-Random Extension of the Lee–Carter Mortality Prediction Model

open access: yesInternational Journal of Computational Intelligence Systems
The Lee–Carter model is a useful dynamic stochastic model to represent the evolution of central mortality rates throughout time. This model only considers the uncertainty about the coefficient related to the mortality trend over time but not to the age ...

Multivariate Control Chart and Lee–Carter Models to Study Mortality Changes

open access: yesMathematics, 2020
The mortality structure of a population usually reflects the economic and social development of the country. The purpose of this study was to identify moments in time and age intervals at which the observed probability of death is substantially different

Lee-Carter mortality forecasting: a multi-country comparison of variants and extensions

open access: yesDemographic Research, 2006
We compare the short- to medium-term accuracy of five variants or extensions of the Lee-Carter method for mortality forecasting. These include the original Lee-Carter, the Lee-Miller and Booth-Maindonald-Smith variants, and the more flexible Hyndman ...

Application of Machine Learning to Mortality Modeling and Forecasting

open access: yesRisks, 2019
Estimation of future mortality rates still plays a central role among life insurers in pricing their products and managing longevity risk. In the literature on mortality modeling, a wide number of stochastic models have been proposed, most of them ...

Physics-Informed Neural Mortality: Embedding Biological Mortality Laws in Neural Differential Equations for Life-Table Closure and Longevity Uncertainty Quantification

open access: yesMathematics
Deep learning has become the default toolkit for mortality forecasting, yet essentially all existing models are purely data-driven: they fit well in-sample but can produce biologically implausible surfaces and extrapolate poorly to the oldest ages, and ...

Evaluating the Performance of Variants of the Lee-Carter Method for Mortality Forecasting in the Population Projection of the Czech Republic from the Czech Statistical Office 2023–2100

open access: yesDemografie
This article discusses the use of the Lee-Carter model, one of the most widely used methods for mortality forecasting. It also discusses its modified versions, namely the cohort and coherent variants, which were developed to improve the forecast accuracy
