Statistical Estimation of the Coefficient of Pairwise Compatibility for Menu Items
Abstract
The coefficient of compatibility between two menu items is defined as the difference between the conditional and marginal probabilities of selecting one after the other. Maximum likelihood estimates from selection statistics are given, and the asymptotic distribution of the estimator is determined so that test of null hypothesis and confidence intervals regarding the coefficients can be obtained. A method is described for building data base for large joint probability matrices from menu selection data.
