NettetLes méthodes Lee-Carter et log-Poisson constituent des modèles bi-dimensionnels prenant en compte à la fois l’année et l’âge pour déterminer les taux de mortalité. Nettetactual 1989 rates. At first Lee and Carter worried about giving too much weight to a single year, but eventually concluded that it was better to update the age- pattern. The next step in the forecast is to construct a full life table from the age-specific mortality rates. This can be done using standard techniques, so I’ll skip the details.
