Nowadays, different types of automatic systems are used for efficiency rising of a large number of mass decisions
approvals (ex. granting of retail loans). Most of them are based on difficult mathematic-statistical theories and instru
ments widely known as Data Mining. This paper describes the linear scoring model which is one of the simplest but
often used in practice automatic decision approval model. The economic-mathematical meaning of linear scoring is
demonstrated on the example of banking credit activity. This meaning helps practical economists to estimate precisely the given model’s applicability area and to take deliberate decisions.
