  author={Fabio Divino and Denekew Bitew Belay and Nico Keilman and Arnoldo Frigessi},
  journal={arXiv: Applications},
In this work we present a spatial approach to model and investigate mortality data referenced over a Lexis structure. We decompose the force of mortality into two interpretable components: a Markov random field, smooth with respect to time, age and cohort which explains the main pattern of mortality; and a secondary component of independent shocks, accounting for additional non-smooth mortality. Inference is based on a hierarchical Bayesian approach with Markov chain Monte Carlo computations… 


Geographical mortality patterns in Italy: A Bayesian analysis
Abstract In this paper, we present a hierarchical spatial model for the analysis of geographical variation in mortality between the Italian provinces in the year 2001, according to gender, age class,
Bayesian Stochastic Mortality Modelling for Two Populations
An Age-Period-Cohort model is proposed which incorporates a mean-reverting stochastic spread that allows for different trends in mortality improvement rates in the short-run, but parallel improvements in the long run.
Bayesian analysis of mortality data
A Bayesian analysis is adopted, using Markov chain Monte Carlo simulation, to produce the posterior summaries required, which opens the way to richer, more flexible inference summaries and avoids the numerical problems that are encountered with classical methods.
A Bayesian forecasting model: predicting U.S. male mortality.
Results from the forecasts show the Bayesian prediction intervals to be appropriately wider than those obtained from the Lee-Carter method, correctly incorporating all known sources of variability.
Predicting Human Mortality: Quantitative Evaluation of Four Stochastic Models
In this paper, we quantitatively compare the forecasts from four different mortality models. We consider one discrete-time model proposed by Lee and Carter (1992) and three continuous-time models:
Multivariate Functional Time Series Forecasting: Application to Age-Specific Mortality Rates
This study considers the forecasting of mortality rates in multiple populations. We propose a model that combines mortality forecasting and functional data analysis (FDA). Under the FDA framework,
A Bayesian smoothing spline method for mortality modelling
Abstract We propose a new method for two-dimensional mortality modelling. Our approach smoothes the data set in the dimensions of cohort and age using Bayesian smoothing splines. The method allows
The Lee-Carter Method for Forecasting Mortality, with Various Extensions and Applications
Abstract In 1992, Lee and Carter published a new method for long-run forecasts of the level and age pattern of mortality, based on a combination of statistical time series methods and a simple
Bayesian Poisson log-bilinear models for mortality projections with multiple populations
Life insurers, pension funds, health care providers and social security institutions face increasing expenses due to continuing improvements of mortality rates. The actuarial and demographic
Two‐Dimensional Kernel Smoothing of Mortality Surface: An Evaluation of Cohort Strength
Accurate mortality forecasts are of primary interest to insurance companies, pension providers and government welfare systems due to the rapid increase in life expectancy during the past few decades.
