Are forecasting future behavior. 2 shows a timeline relating data used to build predictive models or business intelligence reports. The vertical line in the middle is the time the model is being built (today). The data used to build the models is always to the left: historic data. When predictive models are built to predict a “future” event, the data selected to build the predictive models is rolled back to a time prior to the date the future event is known. 2 Timeline for building predictive models For example, if you are building models to predict whether a customer will respond to an e-mail campaign, you begin with the date the campaign cured (when all the responses have come in) to identify everyone who responded.
