The only study that we are aware of that focused on modeling credit risk specifically for SMEs is a fairly distant article by Edmister (1972). The VaR tools used in the German banking sector to measure credit risk are analysed in a next step. Likewise, credit risk modelling is a field with access to a large amount of diverse data where ML can be deployed to add analytical value.
