Patent number: 8583408Abstract: An enhanced modeling tool associated with an entity may facilitate end-to-end modeling of problems in any application space. The enhanced modeling tool may collect modeling data from a variety of sources, check the collected data, find the best predictor variables for a given target variable, estimate the model, implement the model, and validate the model. The output of each of these steps may be in a standardized format to allow other steps to directly incorporate the output. An additional feature of the system may include a reporting capability that generates supporting documents related to model governance and risk compliance.Type: GrantFiled: March 17, 2011Date of Patent: November 12, 2013Assignee: Bank of America CorporationInventors: Kasilingam Basker Laxmanan, Yudong Chen, Gerald F.
