In this study we derive a novel multi-population LC type model. Specifically, we extend the Bayesian model in czado et. al. (2005) to allow exchangeability between parameters of a group of m populations. In a validation-based examination, the proposed model was found to be beneficial for several...

This paper extends the widely used Lee Carter (LC) model (Lee & Carter, 1992) for mortality projection. We suggest a random walk with drift to model the time parameter of the Bayesian extension of the LC model suggested in Czado et al. (2005). In a validation-based examination, the proposed...
