Zusammenfassung:The invention relates to a logistic regression-based member value quantitative evaluation method. The method comprises the steps of 1) obtaining member original data; 2) preprocessing the obtained member original data to obtain preprocessed formatted data; 3) performing data annotation on the preprocessed formatted data; 4) screening effective features used for inputting a model from the original features of the formatted data; 5) constructing a member value evaluation model including variable segmentation, WOE transformation of variables and logistic regression estimation; and 6) inputting the effective features screened in the step 4) into the constructed member value evaluation model to obtain a member value quantitative evaluation result. Compared with the prior art, the method has the advantages of being objective in evaluation, more suitable for e-commerce platforms such as the B2B iron and steel industry and the like, and the like. 本发明涉及一种基于逻辑回归的会员价值量化评估方法,包括:1)获取会员原始数据;2)对获取的会员原始数据进行预处理,获取预处理后的格式化数据;3
