Credit Scoring And Data Mining
Syllabus 2006/2007
Lectures held ; Fridays January 26 ( Thomas), and Feb 2 (Edelman) and 9 ( Thomas)
Aims and objectives
The course aim is to present a comprehensive review of the objectives, methods and practical implementations of credit and behavioural scoring in particular and data mining in general. It involves understanding how large data sets can be used to model customer behaviour and how such data is gathered,stored and interrogated and it use to cluster, segment and score individuals. The aim is to look at the largest application in more detail. Credit scoring is the process of deciding, whether or not to grant or extend a loan. Sophisticated mathematical and statistical models have been developed to assist in such decision problems.
Syllabus
Day 1.
Session 1: Introduction to Data mining and Credit scoring
What is data mining? Databases, data warehousing and data management. Objectives of data mining :Origins of credit and credit lending to consumers; judgmental approaches; introduction of credit scoring; philosophical approach to credit scoring. Overview of use of scoring systems; how credit scoring fits into lenders risk assessment process; what data is needed; role of credit scoring consultancies; testing the scorecard; relation with information system; application form; role of credit bureau; overrides and manual interventions; need for monitoring ; relationship with portfolio of bank products.
Session 2: Statistical Methods for Scorecard Development
Statistical methods in credit scoring and classification methods in data mining; discriminant functions; logistic regression approach; classification trees; non-parametric approaches; graphical models of statistical connections.
Session 3 : Other Credit Scoring Techniques
Mathematical programming and goal programming approaches; neural networks; genetic algorithms and other combinatorial optimisation approaches; expert systems; support vector machines
Lab class on using techniques to build scorecard
Day 2
Session 4: Practical Issues of scorecard performance
Selecting sample; definitions of good and bad; choice of variables; credit bureau data; discarding variables; weights of evidence; coarse classifying continuous variables; taking non-linear functions of variables; dealing with correlations ; reject inference; adjusting cut-off scores; over-rules and their effect on the scorecards.
Session 5 : Measuring Scorecard performance
