I am building a customer attrition model for a commercial banking client. I am having difficulty defining target variable - customer attrition. In the data set, i can have multiple records for a single customer. Suppose a customer holds multiple accounts (or products) so there would be multiple records for a customer. The question arises - Should i calculate attrition at customer level or multiple models for each products? I know it all depends on the objective of the study. Is it possible to calculate customer attrition at customer level (aggregating information of multiple products)?
