Abstract:
The invention relates to a method for determining a time for retraining a data mining model, including the steps of: calculating multivariate statistics of a training model during a training phase; storing the multivariate statistics in the data mining model; evaluating reliability of the data mining model based on the multivariate statistics and at least one distribution parameter, and deciding to retrain the data mining model based on an arbitrary measure of one or more statistical parameters including an F-test statistical analysis.
