Spatial Statistical Modeling of Insurance Risk An epidemiologist approach to car insurance
(2017) SPAS2017 International Conference on Stochastic Processes and Algebraic Structures – From Theory Towards Applications- Abstract
- Spatial models, such as the Besag, York and Mollie (BYM)model, have long been used in epidemiology and disease mapping. A commonproblem in these subjects is the modelling of number of disease eventsper region; here the BYM models provides a holistic framework for bothcovariates and dependencies between regions.We use these tools to assess the relative insurance risk associated withthe policyholders geographical location. The models are placed in a Bayesianframework, and inference is made using Integrated Nested Laplace Approximation(INLA).The model is applied to car insurance data from If P&C Insurance togetherwith spatial referenced covariate data of high resolution, provided byInsightone. Including spatially dependence in the... (More)
