Nettet1. aug. 2013 · The Lee-Carter method (Lee and Carter 1992) has been applied to middle-term (around 50 years) mortality projections for almost all the countries with reliable data and in normal socioeconomic conditions, and has provided satisfactory results (Lee and Miller 2001; Tuljapurkar et al. 2000). Nettet28. jun. 2024 · Abstract. This paper introduces a neural network approach for fitting the Lee-Carter and the Poisson Lee-Carter model on multiple populations. We develop some neural networks that replicate the structure of the individual LC models and allow their joint fitting by analysing the mortality data of all the considered populations simultaneously. magic vs lakers score https://ewcdma.com
