A machine learning approach based on survival analysis for IBNR frequencies in non-life reserving
Munir Hiabu, Emil Hofman, Gabriele Pittarello
We introduce new approaches for forecasting IBNR (Incurred But Not Reported) frequencies by leveraging individual claims data, which includes accident date, reporting delay, and po…

Replicating and extending chain-ladder via an age-period-cohort structure on the claim development in a run-off triangle
Gabriele Pittarello, Munir Hiabu, Andrés M. Villegas
This paper introduces yet another stochastic model replicating chain-ladder estimates and furthermore considers extensions that add flexibility to the modeling. In its simplest for…

Individual claims reserving using the Aalen--Johansen estimator
Martin Bladt, Gabriele Pittarello
We propose an individual claims reserving model based on the conditional Aalen-Johansen estimator, as developed in Bladt and Furrer (2023b). In our approach, we formulate a multi-s…
