This could include identifying a distribution of knots and multiple ordinal spline functions, where each ordinal spline function is associated with one of the knots. The ordinal spline bases function can be generated using at least one of the ordinal spline functions. | 12-20-2012 |

20130103570 | SYSTEM AND METHOD FOR DETERMINING CREDIT QUALITY INDEX - Electronic modeling of long-term historical financial credit performance of a consumer is described. A plurality of historical time periods originating from an observation point in time occurring in the past are established and a plurality of past credit performance snapshots for a sample consumer population are obtained. A credit risk management computer system computes a credit quality index for each of the past credit performance snapshots of the sample population and for a recent credit performance snapshot of the consumer. An overall credit quality index for the sample population spanning the plurality of historical time periods is likewise computed and a prediction of an overall credit quality index for the consumer spanning the plurality of historical time periods is made. | 04-25-2013 |

20120226616 | VIRTUAL GOODS INCENTIVE SYSTEM - Virtual goods, such as Facebook credits or Farmville animals, are offered as an incentive to acquire new customers or reacquire former customers. Using a simple click-through process, a customer may receive a given number of virtual credits, or a particular virtual item, upon satisfying a given requirement, such as a purchase above a given amount, a subscription to a mailing list, submission of a preference profile, and so on. Initial tests have indicated that a substantial number of customers prefer receiving such virtual items in lieu of a cash rebate or other cash-based discount, even when the actual cost associated with the virtual item is the same as, or lower than the amount of the cash-based discount. In a preferred embodiment, a third-party campaign manager facilitates the execution and management of the incentive campaign. | 09-06-2012 |
20120278247 | VIRTUAL GOODS INCENTIVE SYSTEM - An interface application enables a campaign manager to manage the transfer of virtual credits to a user upon completion of an action that benefits a provider of goods or services. The campaign manager provides a link to the provider of goods or services. When a user clicks through to this link, the interface application directs the user to perform the desired action. Upon completion of the action, the application deposits a credit to the user's virtual account. Because the virtual transaction is performed by the provided interface application, the logistics associated with launching and executing the campaign are low enough to facilitate hi-volume, low-cost incentive programs. | 11-01-2012 |
