Abstract

The invention provides a security customer loss prediction method and system based on Logistic regression, and the method comprises the steps: determining a customer loss index and a data range; screening the customer data according to the customer loss index and the data range; calculating the initial variable according to the screened customer data; carrying out the preprocessing of the initial variable; carrying out the prediction calculation of the customer loss according to the preprocessed initial variable through a Logistic regression model, so as to obtain a customer list with the loss probability being greater than a preset loss probability threshold value. The method achieves the objective analysis of the selected customer data through the Logistic regression model, so as to accurately and objectively predict the customer loss.

Description

technical field [0001] The invention relates to the field of securities, in particular to a method and system for predicting the loss of securities customers based on Logistic regression. Background technique [0002] In recent years, most of the large securities companies have achieved large-scale centralized or regional centralized transactions. To a certain extent, large-scale data centralization can reduce costs and strengthen risk management for securities companies. However, how to increase profit margins centered on customer service?

And these problems are the main problems that securities companies must face in order to survive and gain competitive advantage in the transition period. Among them, customer loss is a common business problem faced by the securities industry, especially when the cur...
