The Investigation of a Forward-Rate Mortality Framework

Risks, 2019
Stochastic mortality models have been developed for a range of applications from demographic projections to financial management. Financial risk based models built on methods used for interest rates and apply these to mortality rates.

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

Journal 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.

Gaussian and Affine Approximation of Stochastic Diffusion Models for Interest and Mortality Rates

Risks, 2013
In the actuarial literature, it has become common practice to model future capital returns and mortality rates stochastically in order to capture market risk and forecasting risk. Although interest rates often should and mortality rates always have to be

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

Ecology 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 ...

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

Applied 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.

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

FinTech, 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%.

GBS‐MeDIP: A method for the simultaneous identification of genetic and epigenetic variants in tumors

FEBS Open Bio, EarlyView.
GBS‐MeDIP combines DNA sequencing with enrichment of methylated DNA to profile genetic and epigenetic variation in the same reduced genomic fraction. Applied to gastric cancer and parathyroid tumors, it identifies sequence variants, copy number changes, and differentially methylated regions together, helping distinguish true epigenetic changes from ...

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.

PLoS 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 ...

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

Mathematical 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. An

Anticoagulation Treatment Response Among Phenotypic ESUS Clusters: Evidence From CASPR

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To evaluate treatment effect heterogeneity across phenotypic clusters of patients with cryptogenic embolic stroke using causal inference methods. Methods From a retrospective, multicenter cohort of patients with cryptogenic embolic stroke, we estimated the treatment effect of anticoagulation versus antiplatelet therapy in patients ...
