statistical-analysis-project's Introduction

Statistical analysis project

本项目是管理学院统计学习课程的课程项目,项目要求在文件 ‘2018春季学期-机器学习-大作业说明’ 中

项目说明

在当前的数据信息社会中,个人信用已变得十分重要,其关乎着生活中的出行,消费,借贷等等各个方面。而商业银行和金融借贷公司为控制自身风险,往往需分析客户办理借贷后的各项行为,进而来判别客户是否有违约风险,以此作为公司的预警系统,为后续的针对性操作提供帮助。本次大作业的内容即为分析客户个人行为数据,建立适当的模型,判断客户在未来是否会出现逾期行为。

该数据为客户在某银行办理信用卡后一段时间内的个人行为数据,包括账户基本信息,交易行为,消费行为,信用卡还款行为,分期行为,和取现行为。目标变量target代表客户在未来是否出现逾期(1为有逾期,可称为坏客户;0为未逾期,可称为好客户),其他各个变量具体的名称和含义见附件变量说明表。数据中的缺失值已做过简单处理,处理方式见附件变量说明表,也可自行变更处理方式。数据并未提供测试集,可自行将数据分为训练集与测试集,给出模型分别在训练集和测试集上的表现即可,如给出ROC曲线,KS曲线,召回率,准确率,F1值等。建模方法可使用logistic regression, classification tree, random forest, svm, boosting(gbdt,xgboost , catboost etc.)等等。
