Methods and apparatus to calibrate a choice forecasting system for use in market share forecasting are disclosed. An example disclosed method comprises obtaining market research data to determine a plurality of choice probabilities and a plurality of segment weights, each choice probability representing a probability that a respective population segment will choose a respective alternative from a plurality of alternatives and each segment weight representing a weight of a respective population segment in an overall population, and performing a calibration procedure to calibrate the plurality of choice probabilities and plurality of segment weights, the calibration procedure configured to preserve before and after calibration relative contributions of a pair of population segments to a first choice share corresponding to a first alternative, the first choice share for the first alternative determinable from the plurality of segment weights and a subset of the plurality of choice probabilities corresponding to the first alternative.
