Stochastic Panel-Data Models of Urban Shopping Behaviour: 4. Incorporating Independent Variables into the NBD and Dirichlet Models

Environment and Planning A, 1985, vol. 17, issue 3, 319-331

Abstract: In this paper the authors describe the way in which the NBD and Dirichlet models of consumer behaviour may be extended to include independent or exogenous variables. Such methods allow the predictions obtained from these models to be disaggregated, that is, to be made conditional on the values of the exogenous variables. Empirical examples are presented of repeat buying of a branded good and at an individual store (for the NBD model), and of multistore purchasing (for the Dirichlet model).
