Abstract
Abstract A loss control system for an insurance classification plan has a policy holder database, a predictive apparatus and a derived actual loss ratio generator. The policy holder database generates signals indicative of the premium, actual loss, a one a plurality of classification plan variable values and an actual loss ratio for each policy holder. The predictive apparatus generates a plurality of predicted loss ratio signals indicative of predicted loss ratios of the policy holders. The derived actual loss ratio generator generates signals which are indicative of a difference between the predicted loss ratio and the actual loss ratio of the policy holders.
