Modeling Purchases as Repeated Events
提出一个统计模型，利用所有历史购买信息预测未来购买次数和时机，以酸奶购买为例展示其管理应用。
We put forward a statistical model for interpurchase times that incorporates all current and past information available for all purchases as time runs along the calendar time scale. It delivers forecasts for the number of purchases in the next period, as well as for the timing of subsequent and consecutive purchases. Purchase occasions are viewed as a counting process that counts the recurrent purchases for each house-hold as they evolve over time. We illustrate our model for yogurt purchases and highlight its managerial implications.
