Actuarial Modelling of Claim Counts: Risk Classification, Credibility and Bonus-Malus Systems
TL;DR: In this article, the authors summarize the most recent developments in the field, presenting ratemaking systems, whilst taking into account exogenous information, and summarise the relationship between experience rating systems and risk classification.
Journal ArticleDOI
Using Mixed Poisson Processes in Connection with Bonus-Malus Systems
Jean-François Walhin,José Paris +1 more
TL;DR: In this article, a parametric method for the construct of bonus-malus systems is proposed, thanks to sunple mathematms, and compared with a non-parametric one that has not yet been used m the actuarial hterature.
Journal ArticleDOI
Statistical procedure for improving the precision of the measurement of the essential work of fracture of thin sheets
TL;DR: In this paper, a statistical procedure is proposed which allows to determine easily and accurately this critical ligament length, after rejection of the specimens having too small ligament lengths, we is obtained by extrapolation of the remaining data for zero ligaments length.
Journal ArticleDOI
Setting a bonus-malus scale in the presence of other rating factors: Taylor's work revisited
TL;DR: In this article, an analytic analogue to the simulation procedure described in Taylor (1997) is proposed, and applied to a Belgian data set and discussed the interaction between a priori and a posteriori ratemakings.
Journal ArticleDOI
Stochastic projection for large individual losses
TL;DR: In this article, the authors investigate how to estimate the ultimate value of large losses based on the development of individual losses and therefore allow to compute the netting impact of excess of loss reinsurance.
