Abstract:
Several heterogeneous multivariate probit models are used to analyze market baskets purchased by households. Each of these models is related to one group of product categories contained in seven prior partitions formed for a total of 25 product categories. The best model in terms of cross-validated log likelihood found considers all categories as one group, i.e., it does not split the 25 categories into two or more groups. In the next step of this project, we will compare this result to multivariate probit models which are related to a partition which is not fixed beforehand, but determined by stochastic model search.
