METHODS AND APPARATUS TO PERFORM CHOICE MODELING WITH SUBSTITUTABILITY DATA
First Claim
1. A method to calculate choice probability, comprising:
- receiving base choice probability values for a respondent, wherein the base choice probability value is associated with a product;
receiving a respondent substitutability factor associated with the product;
identifying, with a cluster analysis engine, a primary product and a secondary product and generating a subrespondent associated with the secondary product; and
calculating, with a cross sourcing engine, a modified choice probability for the subrespondent for the secondary product based on the respondent substitutability factor and the base choice probability values associated with the secondary product.

Abstract
Methods and apparatus are disclosed to perform choice modeling with substitutability data. An example method includes receiving base choice probability values for a respondent, wherein the base choice probability value is associated with a product, receiving a respondent substitutability factor associated with the product, identifying, with a cluster analysis engine, a primary product and a secondary product and generating a subrespondent associated with the secondary product, and calculating, with a cross sourcing engine, a modified choice probability for the subrespondent for the secondary product based on the respondent substitutability factor and the base choice probability values associated with the secondary product.

7. A method to calculate choice probability, comprising:
-
performing a card sort for products within a category using a card sort engine, the card sort engine retrieving information indicative of product similarity; generating, with a substitutability matrix engine, a triangular matrix with the information indicative of product similarity; transforming the triangular matrix into a list of product subcategories; calculating substitutability values between the subcategories based on matrix values for pairs of products selected between product subcategories; and invoking a multinomial logit model to generate choice probabilities based on the substitutability values and a virtual shopping exercise. - View Dependent Claims (8, 9, 10, 11)
