Econometric engine
First Claim
1. A computer-implemented method for creating a product sales model for each of a plurality of products, the method being implemented as a plurality of program instructions stored in a computer readable storage medium in a computer system, said method comprising the steps of:
- creating, using the computer system, a plurality demand groups, wherein each demand group is a user defined group of highly substitutable products, further wherein each demand group is a set of, at least one product and at least one of the demand groups is, a set of at least two products;
creating, using the computer system, a demand group sales model as a function of price wherein said demand group sales model models sales for each demand group, further wherein said demand group sales model provides a single model for modeling sales of all of the products in each said demand group;
creating, using the computer system, a market share model wherein said market share model determines the fraction of the sales of each demand group comprised by each product; and
creating, using the computer system, said product sales model by combining said demand group sales model and said internal market share model, wherein said product sales model models sales for individual products, further wherein said product sales model combines said demand group sales model and said internal market share model to produce said product sales model for individual products.

Abstract
A method for creating a sales model for a plurality of products is provided. Generally a plurality demand groups are created, where each demand group is a set of at least one product and wherein at least one of the demand groups is a set of at least two products. A sales model is created for each demand group. A market share model is created for each product in each demand group.
In addition, an econometric engine for modeling sales as a function of price is provided. An imputed variable generator and a coefficient estimator coupled to the imputed variable generator form the econometric engine, where imputed variables generated by the variable generator are used by the coefficient estimator to create a sales model.

3. A computer program product in a computer-readable media, the computer program product comprising:
computer program instructions which, when executed by a computer, cause the computer to generate an econometric engine for modeling sales as a function of price, the engine further comprising; an imputed variable generator for generating imputed econometric variables including a base price variable and a base volume variable, wherein said base volume variable represents the volume of product units sold in the absence of discount pricing or other promotional effects; and a coefficient estimator coupled to the imputed variable generator, and wherein imputed variables generated by the variable generator are used by the coefficient estimator to create a demand group sales model as a function of price, wherein said demand group sales model provides a single model for modeling sales of all of the products in each said demand group, wherein each said demand group is a user defined group of highly substitutable products, an internal market share model, and a combined product sales model wherein said product sales model models sales for individual products, further wherein said combined product sales model combines said demand group sales model and said internal market share model to produce said product sales model for individual products. - View Dependent Claims (4, 8, 10)
