Indicator category | Indicator name | Financial risk implication | Preprocessing method |
|---|---|---|---|
Global indicators | Network density | Systemic connectivity strength | z-score normalization |
Network association | Risk contagion reachability | log transformation | |
Network hierarchy | Structural inequality | Min–Max normalization [0,1] | |
Node indicators | Weighted degree centrality | Total institutional risk exposure | Weighted by asset size |
Weighted betweenness centrality | Risk transmission hub role | Percentile rank transformation | |
Weighted clustering coefficient | Local risk clustering | Tertile discretization |
