Please predict whether this patent is acceptable.PATENT ABSTRACT: A system and method are disclosed for classifying a record of data when the record of data does not contain class membership information. In one example, summary data is utilized with predictive modeling to predict the age range of a user of a line of service. A prior probability that a user within the summary data belongs to a respective class, a first conditional probability of a first predictor within the summary data and a second conditional probability of a second predictor within the summary data are calculated. For each record of data, a probability of class membership is calculated based on the calculated prior probability and the first and second conditional probabilities.
