Several approaches for subset recovery and improved forecasting accuracy have been proposed and studied. One way is to apply a regularization strategy and solve the model selection task as a continuous optimization problem. One of the most popular approaches in this research field is given by...

One of the main challenges for life actuaries is modeling and predicting the future mortality evolution. To this end, several stochastic mortality models have been proposed in literature, starting from the pivotal approach of the Lee-Carter model. These models essentially use the ARIMA processes...

We analyse models for panel data that arise in risk allocation problems, when a given set of sources are the cause of … an aggregate risk value. We focus on the modeling and forecasting of proportional contributions to risk. Compositional …

In this paper we provide a new expression for the true one-year prediction uncertainty within the chain-ladder model of Mack, which can be useful for quantification and sensitivity analysis.We also show that, in case sufficiently large sized claims trapezoids are considered (which might not be...

The aim of this contribution is to revisit, clarify and complete the picture of uncertainty estimates in the chain-ladder (CL) claims reserving method. Therefore, we consider the conditional mean square error of prediction (MSEP) of the total prediction uncertainty (using Mack's formula) and the...
