Comparative Study of Lee Carter and Arch Model in Modelling Female Mortality in Nigeria

open access: yesUMYU Scientifica Journal, 2022
Using Nigeria mortality data from 2009 to 2020, this study compares and contrasts how well the Lee-Carter and ARCH models performed. Singular value decomposition (SVD) method, Langrage multiplier test, and autoregressive conditional heteroskedasticity ...

Should Selection of the Optimum Stochastic Mortality Model Be Based on the Original or the Logarithmic Scale of the Mortality Rate?

open access: yesRisks, 2023
Stochastic mortality models seek to forecast future mortality rates; thus, it is apparent that the objective variable should be the mortality rate expressed in the original scale. However, the performance of stochastic mortality models—in terms, that is,

CALIBRATING THE LEE-CARTER AND THE POISSON LEE-CARTER MODELS VIA NEURAL NETWORKS [PDF]

open access: yesASTIN Bulletin, 2021
AbstractThis paper introduces a neural network (NN) approach for fitting the Lee-Carter (LC) and the Poisson Lee-Carter model on multiple populations. We develop some NNs that replicate the structure of the individual LC models and allow their joint fitting by simultaneously analysing the mortality data of all the considered populations.

Sensitivity and uncertainty in the Lee-Carter mortality model

open access: yesInternational Journal of Forecasting, 2023
Abstract BACKGROUND The Lee-Carter model (LC) is widely used in research and applications for forecasting age specific mortality, and typically performs well regardless of the uncertainty and often the limited quality of mortality data. OBJECTIVE

Comparative Study of Mortality Rate Prediction Using Data-Driven Recurrent Neural Networks and the Lee–Carter Model

open access: yesBig Data and Cognitive Computing, 2022
The Lee–Carter model could be considered as one of the most important mortality prediction models among stochastic models in the field of mortality.

Identification and Forecasting in the Lee-Carter Model [PDF]

open access: yesSSRN Electronic Journal, 2010
We consider the identification problem for the model of Lee and Carter (1992). The parameters of this model are known only to be identified up to certain transformations. Forecasts from the model may therefore depend on the arbitrarily chosen identification scheme. A condition for invariant forecasts is proposed.

A New Fourier Approach under the Lee-Carter Model for Incorporating Time-Varying Age Patterns of Structural Changes

open access: yesRisks, 2022
The prediction of future mortality improvements is of substantial importance for areas such as population projection, government welfare policies, pension planning and annuity pricing.

Longevity risk—Its financial impact on pensions

open access: yesScientific African, 2022
We study the financial impact of longevity risk on defined benefit (DB) pension plan liabilities using the 2010 Ghana population census, and the Lee-Carter model. We compare the usual Lee-Carter model to an extended version. While we observe that Ghana’s

Multiple mortality modeling in Poisson Lee–Carter framework [PDF]

open access: yesCommunications in Statistics - Theory and Methods, 2015
The academic literature in longevity field has recently focused on models for detecting multiple population trends (D'Amato et al., 2012b; Njenga and Sherris, 2011; Russolillo et al., 2011, etc.). In particular, increasing interest has been shown about "related" population dynamics or "parent" populations characterized by similar socioeconomic ...
