1. A computer-implemented method of assessing a predictive model, comprising:
- accessing, using one or more data processors, a predictive model for scoring transactional data and data associated with a time period;
generating, using the one or more data processors, one or more predictions using the predictive model and the data;
calculating, using the one or more data processors, a baseline performance metric for the predictive model based upon the predictions;
accessing, using the one or more data processors, new data associated with a new time period that is later than the time period;
generating, using the one or more data processors, one or more new data predictions using the predictive model and the new data;
calculating, using the one or more data processors, an updated performance metric for the predictive model based upon the new data predictions;
comparing, using the one or more data processors, the baseline performance metric and the updated performance metric to determine an indication of predictive ability decay for the predictive model; and
performing, using the one or more data processors, a corrective action for the predictive model when the indication of predictive ability decay reaches a threshold.

Abstract
Computer-implemented systems and methods for updating champion predictive models that operate within a production environment. A system and method can include evaluating the predictive model performance of a champion predictive model. Based upon an indication of decay of predictive model performance of the champion predictive model, a corrective action is performed to correct the performance of the champion predictive model.
