Abstract: Example methods, systems, and computer readable storage media to predict purchasing behavior are disclosed. A disclosed example method includes creating a model based on first purchase data and demographic information. The first purchase data and demographic information is associated with panelists. The first purchase data is collected via both a home scanning system and via a frequent shopper system. The example method includes applying the model to consumer data to predict second purchase data. The consumer data corresponds to consumers participating in the frequent shopper system who are not panelists of the home scanning system. The example method includes creating a report based on the second purchase data.
