Discrete choice modeling, volumetric choice modeling, and conjoint modeling are analytical methods used to simulate real-world consumer purchasing behavior. Our Advanced Analytics consultants set up carefully controlled experiments in which consumers are simply asked to choose how many of each product they would buy, given predetermined sets of realistic conditions. Consumers are not consciously aware of what is being measured. The brands are presented visually (including 3D simulation), if possible, in the context of advertising, pricing, packaging, features, promotion, and other variables. The importance of each marketing variable is then derived mathematically.
