摘要
A system that estimates elasticity and inventory effect for a product pricing or forecasting system receives a sales condition relationship for an item at a store, the relationship comprising an elasticity parameter, an inventory effect parameter and a sales constant. The system receives a demand model for sales of the item in terms of the elasticity parameter and the inventory effect parameter and a base demand for the item selling at the store. The system estimates the sales constant, the estimating comprising generating a theta parameter by taking logarithms of the sales condition relationship. The system uses linear regression to estimate a logarithm of the sales constant and a value of the theta parameter. The system determines a relationship between the elasticity parameter and the inventory effect parameter based on the value of the theta parameter.
