In order to achieve the proposed objective and to show empirical evidence, an artificial intelligence method, Rough Set theory, has been employed. The empirical evidence shows that common risk factors employed by insurance companies are good explanatory variables for classifying car policyholders' policies. In addition, the BM level variable slightly increases the explanatory power of the a priori risks factors.engAtribución-NoComercial-CompartirIgual 3.0 Españahttps://creativecommons.org/licenses/by-nc-sa/3.0/es/journal articlehttps://search.proquest.com/docview/1753204704/fulltextPDF/BD3CA6DDF70040A6PQ/1?accountid=14514open accessAutomobile insurance companyRisk factorsBonus malus systemRough set theoryArtificial intelligenceInteligencia artificial (Informática)Seguros1203.04 Inteligencia Artificial5304.05 Seguros
