Incidents considered by the Qi predicative model are a cleaned-up version of the IHS Markit casualty information, similar to what was used in SVIS.
These could include fire, grounding, collisions etc.
The model in Qi is not predicating the type of incident, but rather the likelihood of a incident occurring in the next 12 months.
