Measures of association applied to operational risks

Association rules are a basic analysis tools for unstructured data such as accident reports, call centres recordings and CRM logs.

We will also present a new graphical display of association rules that permits effective clustering of associations with a novel association rule called the Relative Linkage Disequilibrium
