An experimental comparison of classification techniques in debt recoveries scoring: Evidence from South Africa's unsecured lending market

作者:

Highlights:

• GAM with a GEV link function outperforms standard credit scoring techniques.

• An outcome period between 3 and 12 months adequate for behavioural scoring.

• Widely used out-of-sample testing alone is misleading.

• Flawed AUC very similar to proposed alternative the H-measure.

• Implementation of GAM for recoveries scoring in a South African context presented.
