The aims and objectives of the Statistical Methods in Retail Financial Services Research Group are:

  • To apply statistical methods in the financial sector of industry; and

  • To develop new statistical methodology arising from the novel challenges presented by these applications.

It is very apparent that the level of sophistication of the methods and tools used by the banks to control their retail credit operations is increasing rapidly, and we aim to continue to be in the vanguard of this development. Our research involves all aspects of mathematics and statistics relating to the retail finance industry, including fraud detection, portfolio modelling, default correlation and risk management.

We have numerous links with organisations within the retail banking sector, and are always involved in discussions with banks and other financial bodies about possible collaborations or research sponsorships.  Previous projects have been sponsored by Fair Isaac, Link Financial, and other bodies.

Specific areas of research interest within the Statistics for Retail Finance group:

  • Evaluating scorecards (Hand, Anagnostopoullos, Adams)
  • Fraud detection (Hand, Adams, Heard)
  • Inclusion of macroeconomic conditions on credit risk (Bellotti)
  • Use of survival and panel models for credit risk (Bellotti)
  • Applications of machine learning in credit risk modelling (Bellotti)
  • Stress Testing (Bellotti)
  • Modelling Loss Given Default (Bellotti)
  • Applications of graph mining to portfolio credit risk and fraud detection (Missaoui)

The group is part of the Quantitative Financial Risk Management Centre (QFRMC). This is a research consortium run from the Department of Mathematics at Imperial College, the School of Management at the University of Southampton, and the University of Edinburgh Business School. It was established by the Engineering and Physical Sciences Research Council, with additional funding from the Economic and Social Research Council and the Institute of Actuaries. It carries out research and organises conferences and other meetings addressing issues in the retail financial services sector, in collaboration with banks, credit agencies, and other bodies
