Power Law of Customers' Expenditures in Convenience Stores
arXiv:0802.0105 · doi:10.1143/JPSJ.77.035001
Abstract
In a convenience store chain, a tail of the cumulative density function of the expenditure of a person during a single shopping trip follows a power law with an exponent of -2.5. The exponent is independent of the location of the store, the shopper's age, the day of week, and the time of day.
