An Evaluation of the Application of Minimum Chi-Square Procedures to Stochastic Models of Brand Choice, Journal of Marketing Research
This paper investigates the small sample properties of minimum chi-square estimates of the parameters of stochastic brand choice models. It also describes and evaluates a statistical test which is appropriate for discriminating between two stochastic brand choice models when one is a constrained version of the other.
