Confirmatory Analysis of Aggregate Hierarchical Market Structures: Inferences from Brand-Switching Behavior
开发了一个概率模型，利用品牌转换数据在聚合层面检验假设的层次市场结构，并通过软饮料数据进行了方法演示。
A probabilistic model is developed for testing hypothesized hierarchical market structures at the aggregate level using brand-switching data. Each hypothesized structure is represented by a directed graph and its parameters are estimated by using log-linear modeling techniques. As an illustration, the method is applied to data on soft drinks.
