Introduction to credit scoring
New date: 11-12 August

This two day introductory workshop provides a full overview of all credit scoring related concepts, from model development to validation and stress testing, and is ideal for newly hired credit risk personnel or credit risk professionals wishing to develop their Basel II credit risk modeling skills.  Attendance will provide access to approaches designed to add practical value in both regulatory and business contexts.  Attendees will gain practical insights into recent developments and emerging practice being employed within leading banks and other consumer lending institutions. 

 

The key objectives are:

·         Learn how to develop PD, LGD and EAD models

·         Providing insights into model monitoring using both backtesting and benchmarking procedures

·         Discuss the importance of qualitative model validation

·         Discuss how to stress test credit risk models using both sensitivity and scenario analysis

·         Provide new insights into dealing with low default portfolios

Next to the theoretical concepts and case studies, software demos on both Matlab and SAS for credit scoring will be given:

     Developing a Credit VaR System with MATLAB
During this presentation, it will be demonstrated how MATLAB can be used to develop a model to compute the credit VaR of a portfolio of bonds. Since a typical end user of such a system is not a MATLAB developer, the demonstration will also show how the MATLAB algorithms can be integrated within an Excel front end. This Excel application can then be shared with users that don't have access to MATLAB. The computation of the credit VaR requires a robust credit rating system and an algorithm to compute transition probabilities. It will be shown how the statistical tools can be used to develop these algorithms.
     Using SAS and SAS Enterprise Miner for scorecard construction
In this demo, we will illustrate how to construct a scorecard using SAS and SAS Enterprise Miner. Using real-life application scoring data, we will illustrate how to do coarse classification, weights of evidence coding, scorecard construction and alignment.
