A cohort-based extension to the Lee-Carter model for mortality reduction factors. (English) Zbl 1168.91418

Summary: The Lee-Carter modelling framework is extended through the introduction of a wider class of generalized, parametric, nonlinear models. This permits the modelling and extrapolation of age-specific cohort effects as well as the more familiar age-specific period effects. The choice of error distribution is generalized.
