TRANSACTION DATA ANALYSIS AND DETERMINATION OF QUANTITATIVE CRITERIA OF CUSTOMER'S LOYALTY
Investigation of power distributions remains an actual scientific problem from theoretical as well as practical points of view. Behavior of economic agents, namely dynamics of customer's purchases at retail networks was studied as a subject area of the current research. It was discussed which pragmatically valuable conclusions could be drawn from the fact that observed economic indicators reveal the power-law distribution and by calculating reliable estimates of this distribution parameters. Several examples were used to show how such analysis made it possible to formalize important expert's terms and concepts in particular by providing quantitative measures of client's loyalty.
