ABSTRACT:
A computer-implemented method estimates model parameters for a product. The method includes storing transaction data from customer sales in a database. The transaction data includes a product and a store. The database includes a hierarchical categorization of the products or the stores. The method includes generating a model for each product at each store in the database. The models include model parameters. The method includes aggregating first and second sets of model parameters from a first set of products occupying a first node of the hierarchical categorization and a second set of products occupying a second node of the hierarchical categorization, weighting the first and second sets of model parameters, and storing the average of the weighted first and second sets of model parameters in the database as the model parameters for a model of a product.
