After a brief presentation of the methodology we develop an exploratory analysis of the portfolio both from a frequency and a severity point of view. Using the main conclusions of this exploratory analysis we estimate our models. We use a log link for both frequency and severity, i.e. we define a multiplicative tariff. When modelling the frequency we use a Poisson regression model with over dispersion and we introduce the bonus-malus in force in the company as an offset since the definitions of a new bonus malus system was outside our setup. Once the models are estimated we define a tariff structure and, finally, in the last chapter we analyze the results and take some conclusions.engTarifa AutomóvelModelos Lineares GeneralizadosSeguradorasTarifaçãoDistribuição PoissonDistribuição GammaCobertura Responsabilidade CivilCobertura Danos PrópriosAutomobile TariffGeneralized Linear ModelsGamma distributionInsurance companiesPoisson distributionPricingCollision and Rollover CoverageThird Party Liability Coveragemaster thesis
