Abstract: An apparatus, computer-readable medium, and computer-implemented method for determining effectiveness of a targeting model, including setting target variables corresponding to an initial group of consumers, the initial group of consumers corresponding to a subgroup of an experimental group of consumers which is larger than the initial group of consumers, applying the targeting model to an experimental set of consumer data corresponding to the experimental group of consumers to generate a plurality of experimental scores which score the experimental group of consumers according to projected fit with the target profile, identifying any experimental scores in the plurality of experimental scores which correspond to the initial group of consumers, and determining an effectiveness of the targeting model with respect to the target profile based at least in part on the target variables and one or more metrics which quantify the identified experimental scores relative to the plurality of experimental scores.
