| Popis: | Demographic projections contain uncertainty and probabilistic models aim to quantify it. This paper develops probabilistic projections of Life Expectancy at birth for Argentina for the period 2025-2100 based on the Bayesian Hierarchical Model. Raftery et. to the. (2013) develop a model that allows estimating the rate of increase in life expectancy of a country using previous data from that country, and taking into account past patterns observed in all other countries. Then Raftery (2014) uses the female gap model to develop life expectancy in males. For this purpose, three adjustment periods are evaluated and the results are analyzed based on the selection of the most appropriate one; life expectancy for men and women, its trend and the gap between the two. Finally, the estimated results are compared with the official data from the national statistical agency. The BHM presents plausible results together with a measure of associated un-certainty that allows deciding until when the forecasts would be reliable or reportable, however, the base period includes projections as input data, generating a paradox of using projections to project. The difference that occurs in the projections for men shows the importance in the model of including or not the last point of the data series. Although the probabilistic models represent great advances, details remain to be discussed, such as the base period and its relationship with official sources (whether estimates or projections. |
