The method of claim 4 , further comprising the steps of: storing, by at least one data processor, a plurality of consumer clusters; storing, by at least one data processor and for each combination of a consumer cluster and an entity cluster, a risk factor indicative of a likelihood that transactions by consumers in the consumer cluster with entities within the entity cluster are fraudulent; determining, by at least one data processor, a current consumer cluster associated with the consumer; and applying, by at least one data processor, the risk factor of the combination of the current consumer cluster and the entity cluster to the predictive model.
