A generalized linear model with smoothing effects for claims reserving

Claims Reserving Using Tweedie’s Compound Poisson Model

We consider the problem of claims reserving and estimating run-off triangles. We generalize the gamma cell distributions model which leads to Tweedie’s compound Poisson model. Choosing a suitable parametrization, we estimate the parameters of our model within the framework of generalized linear models (see Jørgensen-de Souza [2] and Smyth-Jørgensen [8]). We show that these methods lead to reaso...

Model risk in claims reserving within Tweedie’s compound Poisson models

In this paper we examine the claims reserving problem using Tweedie’s compound Poisson model. We develop maximum likelihood and Bayesian Markov chain Monte Carlo simulation approaches to fit the model and then compare estimated models under different scenarios. The key point we demonstrate relates to comparison of reserving quantities with and without model uncertainty incorporated into the pre...

Recent Development in Claims Reserving

This contribution deals with recent development in the field of mathematical loss reserving via Chain Ladder that is regarded as the most popular method for setting technical reserves in non life insurance. It could be formulated deterministically or via a stochastic model. However there are some drawbacks of using this method automatically that will be discussed. Its generalisation Munich Chai...

A Simulation Procedure for Comparing Different Claims Reserving Methods

Model Uncertainty in Claims Reserving within Tweedie’s Compound Poisson Models

In this paper we examine the claims reserving problem using Tweedie’s compound Poisson model. We develop the maximum likelihood and Bayesian Markov chain Monte Carlo simulation approaches to fit the model and then compare the estimated models under different scenarios. The key point we demonstrate relates to the comparison of reserving quantities with and without model uncertainty incorporated ...
