Description

The co-occurrence frequency of each ordered pair of risk factors across all 232 events was calculated, and this frequency was assigned as the weight of the directed edge between the corresponding nodes. In this way, a 29×29 adjacency matrix for food accidents in K-12 school canteens was constructed.
