Abstract: A system for validating models for predicting a client behavior event includes a development module and a validation module. The development module is configured to receive a use case corresponding to the client behavior event and select a subset of variables correlated to the client behavior event. The validation module is configured to select a first model from models that predict client behavior event using the selected subset of variables. The development module selects the first model based on a predicted lift of the first model. The validation module applies the first model to client data acquired subsequent to the selection of the first model. The validation module compares the predicted lift of the first model to an actual lift of the first model as applied to the client data. The validation module selects one of the first model and a different model in response to the comparison.
