    Abstract:

    Aiming at the problem that the output of the users’sensitivity analysis model based on the logistic regression is complex and not easy to understand and apply, an implementation method of the users’outage sensitivity score card based on logistic regression model is proposed.First, it extracts the attribute data related with users’outage sensitivity from the State Grid marketing business sys tem and 95598 system, and selects the high predictive attributes through the information value.Then, the weight of evidence of each attribute value is calculated, and users’outage sensitivity analysis model is constructed Finally, the users’outage sensitivity score card is constructed based on the output parameter of sensitivity analysis model and the weight of evidence values.The method is verified by the actual data and the verification achieves good results.
