Two Stochastic Multidimensional Choice Models for Marketing Research
介绍并扩展了两个用于分析成对选择数据的概率多维模型，包括游走向量模型和游走理想点模型，并提供了它们在14个止痛药品牌消费者选择中的应用示例，以辅助营销决策。
Two recently developed probabilistic multidimensional models for analyzing pairwise choice data are introduced, discussed in terms of their differential properties, and extended in several ways. The first one, the wandering vector model, was originally suggested by Carroll [12] and extended by De Soete and Carroll [30]. The second model, called the wandering ideal point model, is a more recently proposed [32] unfolding analog of the wandering vector model. A general maximum likelihood estimation method for fitting the various models described is mentioned, as well as a statistical test for assessing the goodness of fit. Finally, an application of the models is provided concerning consumer choice for some 14 brands of over‐the‐counter analgesics to illustrate how such models can be gainfully utilized for marketing decision making concerning product positioning.
