CS 298 Final Project Report . 1. The goal of the credit score is assess how likely people are to pay back the loan, but the model isn't perfect. The one we are going to focus on in this article is called credit risk scoring. Traditional credit scoring uses a scorecard method which weights various factors including payment history, dept burden, length of credit history, types of credit used, and recent credit The added nuance allows more sophisticated metrics to be used to interpret and evaluate the predicted probabilities. Credit scoring has much to offer to microfinance institutions and smaller banks. The banking industry has long used credit scoring to determine credit riskthe likelihood a particular loan will be paid back. The module is a perfect blend of theoretical and practical implementation of key credit risk scorecards and regulatory models on the Python platform. First decile should contain highest probability score. Thus, the Here are the scores and the payback status: Each individual is classified as a good or bad credit risk depending on the set of attributes.
