User Based Collaborative Filtering

[nickwallen]

Can user-based collaborative filtering help predict a customer's purchase?

Item -> Plan Options
User -> Customer
User Attributes -> State, Location, Car Age, etc, etc
Ratings -> The number of times a user shopped for a particular option. A user's actual purchase might be weighted to indicate a much higher rating.
