Lee-Carter goes risk-neutral: an application to the Italian annuity market [PDF]

, 2005
We consider a class of stochastic intensities of mortality that generalizes the model proposed by Lee and Carter (1992), allowing general diffusions to drive the mortality time-trend.

A State-Space Estimation of the Lee-Carter Mortality Model and Implications for Annuity Pricing

, 2015
In this article we investigate a state-space representation of the Lee-Carter model which is a benchmark stochastic mortality model for forecasting age-specific death rates.

Lee Carter mortality forecasting: application to the Italian population [PDF]

, 2005
In this paper we investigate the feasibility of using the Lee-Carter methodology to construct mortality forecasts for the Italian population. We fit the model to the matrix of Italian death rates for each gender from 1950 to 2000. A time-varying index of

Evaluating machine learning models for neonatal mortality prediction in data-scarce settings: a case study of Ghana

Journal of Electrical Systems and Information Technology
Neonatal mortality is a persistent challenge in low-resource countries, including Ghana, where achieving the Sustainable Development Goal (SDG) 3.2.2 target by 2030 requires effective forecasting strategies.

Insight into the dynamics of non-Newtonian Casson fluid over a rotating non-uniform surface subject to Coriolis force

Nonlinear Engineering, 2020
Casson fluid model is the most accurate mathematical expression for investigating the dynamics of fluids with non-zero plastic dynamic viscosity like that of blood. Despite huge number of published articles on the transport phenomenon, there is no report
