+Keep the following in mind when you build a prediction:
+
+- Segment lets you predict the likelihood of a customer performing multiple events. 
+- You can choose a time period of 15, 30, 60, 90, or 120 days. 
+- You have granular control over the events Segment factors into the predictive model. By default, Segment's model makes predictions on all events sent to Engage. Segment lets you exclude events you don't want included by unselecting **Include all events**, then filtering out any events you want excluded from the model.
