Problem. We are trying to design custom segmentation option for visitor registration data set, where application user can include and exclude certain parameters. The idea is to give an opportunity for user to create any custom segment he likes.
Data structure. A parameter Opportunity Probability is linked to the Event and Year and shows following for each user, who registered for the event:
Opportunity Probability is 50% when users registers
Opportunity Probability is 100% when user attends the event
If user didn’t register, Opportunity Probability is 0.
Visual representation. Example attached shows selection for new visitors (attended in 2015, but didn’t attend before).
