A Bayesian Approach to Developing a Stochastic Mortality Model for China [PDF]

open access: yesJournal of the Royal Statistical Society Series A: Statistics in Society, 2019
SummaryStochastic mortality models have a wide range of applications. They are particularly important for analysing Chinese mortality, which is subject to rapid and uncertain changes. However, owing to data-related problems, stochastic modelling of Chinese mortality has not been given adequate attention.

Mortality limits used in wind energy impact assessment underestimate impacts of wind farms on bird populations

open access: yesEcology and Evolution, 2020
The consequences of bird mortality caused by collisions with wind turbines are increasingly receiving attention. So‐called acceptable mortality limits of populations, that is, those that assume that 1%–5% of additional mortality and the potential ...

Is Excess Mortality Returning to Pre-Pandemic Levels? A Multi-Model Stochastic Approach for COVID-19: The Spanish Case

open access: yesEpidemiologia
Introduction: This study quantifies excess mortality in Spain during and after the COVID-19 pandemic and assesses whether mortality levels are returning to pre-pandemic patterns.

Deterministic and stochastic trends in the Lee–Carter mortality model [PDF]

open access: yesApplied Economics Letters, 2015
The Lee and Carter (1992) model assumes that the deterministic and stochastic time series dynamics load with identical weights when describing the development of age-specific mortality rates. Effectively this means that the main characteristics of the model simplify to a random walk model with age-specific drift components.

A new method for estimating growth and fertility rates using age-at-death ratios in small skeletal samples: The effect of mortality and stochastic variation.

open access: yesPLoS ONE, 2023
The common procedure for reconstructing growth and fertility rates from skeletal samples involves regressing a growth or fertility rate on the age-at-death ratio, an indicator that captures the proportion of children and juveniles in a skeletal sample ...

Measurement and Impact of Longevity Risk in Portfolios of Pension Annuity: The Case in Sub Saharan Africa

open access: yesFinTech, 2023
Longevity is without a doubt on the rise throughout the world due to advances in technology and health. Since 1960, Ghana’s average annual mortality improvement has been about 1.236%.

Stochastic model for analysis of longitudinal data on aging and mortality [PDF]

open access: yesMathematical Biosciences, 2007
Aging-related changes in a human organism follow dynamic regularities, which contribute to the observed age patterns of incidence and mortality curves. An organism's 'optimal' (normal) physiological state changes with age, affecting the values of risks of disease and death. The resistance to stresses, as well as adaptive capacity, declines with age.

Estimation of Uncertainty in Mortality Projections Using State-Space Lee-Carter Model

open access: yesMathematics, 2020
The study develops alternatives of the classical Lee-Carter stochastic mortality model in assessment of uncertainty of mortality rates forecasts. We use the Lee-Carter model expressed as linear Gaussian state-space model or state-space model with ...

Chapter 1 Stochastic Epidemic Models

open access: yes, 2019
This first chapter introduces some basic facts about stochastic epidemic models.We consider the case of a closed community, i.e. without influx of new susceptibles or mortality.
