The rating system is mostly based on the data analysis concerning the number and the value of claims for individuals or groups \(classes\) of insured people within a given portfolio. Based on a given rating system, the premium for a particular risk is calculated in two stages\: a priori rating and a posteriori rating. In this paper, the process of a priori rating is analyzed with the emphasis on minimum bias methods used for modelling the rating variables."]
