Comparative analysis on the probability of being a good payer
This work studies the causal link between the conduct of an applicant upon payment of the loan and the data that he completed at the time of application. A database of 100 borrowers from a commercial bank is used. Customers are divided into Good and Bad payers, based on the credit history. Linear and logistic regression are applied in parallel to the data in order to estimate the probability of being good for new borrowers. A comparative analysis of the results is made.

In this context an example of the grouping of loyal customers in separate groups ("platinum", "gold", "silver", etc.), using cluster analysis is considered.
