Stochastic Mortality Modelling

Implementation of the family of generalised age-period-cohort stochastic mortality models. This family of models encompasses many models proposed in the actuarial and demographic literature including the Lee-Carter (1992) and the Cairns-Blake-Dowd (2006) models. It includes functions for fitting mortality models, analysing their goodness-of-fit and performing mortality projections and simulations.

Build Status CRAN_Status_Badge downloads

StMoMo (Stochastic Mortality Modelling) is an R package providing functions to specify and fit stochastic mortality models including the Lee-Carter models, the CBD model, the APC model and many other (possibly new) models. The package also includes tools for analysing the goodness of fit of the models and performing mortality projections and simulations.

An overview of the usage and facilities of StMoMo is described in the working paper Andrés M. Villegas, Pietro Millossovich, Vladimir K. Kaishev. “StMoMo: An R Package for Stochastic Mortality Modelling”

News

StMoMo v0.4.1

  • Add Citation file for new JSS publication
  • Correct minor bugs

StMoMo v0.4.0

  • Upgrade plotting function of forecast models (plot.forStMoMo) to include nice fan charts similar to those in the forecast package
  • Change inteface of fit function (fit.StMoMo) to allow simiplified calling using newly defined StMoMoData class
  • Add the possibility of using general arima models (beyond the random walk with drift) for the forecasting and simulation of the period indexes
  • Add new estimation function for the Renshaw and Haberman model implementing the approximate constraint Hunt and Villegas (2015)

StMoMo v0.3.1

  • Change residual plotting function (plot.resStMoMo) to use a more effective divergent colour palette for colourmaps.
  • Change the default plotting limits in residual plotting function to have a symmetric scale
  • Fix formatting issues in logLik, AIC and BIC functions for models fitted with gnm

StMoMo v0.3.0

  • Add optional parameters kt.lookback and gc.lookback to functions forecast.fitStMoMo, simulate.fitStMoMo and simulate.bootStMoMo. These new parameters allow the forecast and simulation of mortality models using only a limited history of the period and cohort indexes

  • Improve documentation of some functions

  • Update package vignette

  • Add citation file

StMoMo v0.2.0

  • First stable version of StMoMo released to CRAN
