For each user, these implementation determine the top preferences, then evaluate the IR
statistics based on a IDataModel that does not have these values. This number is the
"at" value, as in "precision at 5". For example, this would mean precision evaluated by removing the top 5
preferences for a user and then finding the percentage of those 5 items included in the top 5
recommendations for that user.
