上一篇文章基于Python的信用评分卡模型分析(一)已经介绍了信用评分卡模型的数据预处理.探索性数据分析.变量分箱和变量选择等.接下来我们将继续讨论信用评分卡的模型实现和分析,信用评分的方法和自动评分系统. 六.模型分析 证据权重(Weight of Evidence,WOE)转换可以将Logistic回归模型转变为标准评分卡格式.引入WOE转换的目的并不是为了提高模型质量,只是一些变量不应该被纳入模型,这或者是因为它们不能增加模型值,或者是因为与其模型相关系数有关的误差较大,其实建立标准信用评…

信用风险计量体系包括主体评级模型和债项评级两部分.主体评级和债项评级均有一系列评级模型组成,其中主体评级模型可用“四张卡”来表示,分别是A卡.B卡.C卡和F卡:债项评级模型通常按照主体的融资用途,分为企业融资模型.现金流融资模型和项目融资模型等. 我们主要讨论主体评级模型的开发过程. 一.项目流程 典型的信用评分模型如图1-1所示.信用风险评级模型的主要开发流程如下: (1) 数据获取,包括获取存量客户及潜在客户的数据.存量客户是指已经在证券公司开展相关融资类业务的客户,包括个人客户和机构客户:…
