On age-period-cohort parametric mortality rate projections

Abstract: This is the accepted version of the paper.This version of the publication may differ from the final published version. Abstract: An augmented version of the Lee-Carter modelling approach to mortality forecasting, extended to include an age modulated cohort index in addition to the standard age modulated period index is described and tested for prediction robustness. Life expectancy and annuity value predictions, at pensioner ages and various periods are compared, both with and without the age modulated cohort … Show more

“…To simulate the period index, κ t , StMoMo implements a multivariate adaptation of Algorithm 2 in Haberman and Renshaw (2009) without provision for parameter error 15 , while to simulate the cohort index, γ t−x , function simulate uses the equivalent S3 method for objects of class "Arima" provided by the package forecast. For example, the code below produces 500 simulated trajectories for the next 50 years of the six stochastic mortality models fitted previously to the England and Wales male mortality experience:…”

“…The presence of a mild curvature in κ ′ t complicates its forecasting. Although second order ARIMA models should produce good time series fits, Haberman and Renshaw (2009) argue against the use of this approach as it tends to produce excessively wide prediction intervals. Therefore, we instead follow Haberman and Renshaw (2009) and curtail the time series at a perceived point of departure from linearity.…”
