| Abstract(in English) | System underlying purchase activity is hard to understand because of the heterogeneity in consumers’ behavior. However, we could expect to find a specific pattern if we divide purchase records by considering the feature of products and consumers. We, therefore, classified ID-POS data according to product categories, consumer’s attributes and seasons, and analyzed them based on the theory of Taylor’s law: the power-law relationship between the standard deviation and the mean of sales amounts. We found that the nature of Taylor’s law significantly depends on the category or brand of products. |
