Like ItemAverageRecommender, except that estimated preferences are adjusted for the users' average
preference value. For example, say user X has not rated item Y. Item Y's average preference value is 3.5.
User X's average preference value is 4.2, and the average over all preference values is 4.0. User X prefers
items 0.2 higher on average, so, the estimated preference for user X, item Y is 3.5 + 0.2 = 3.7.
