Summary of Best Imputation Options for Centrality Measures.
| Measure | Directed or Undirected | Non-response Type | Size and Centralization | Best Imputation Option |
|---|---|---|---|---|
| Degree | Undirected | Any | Any | Any strategy except Listwise Deletion |
| Bon Power | Undirected | Central Nodes | Any | Model-Baseda |
| Betweenness | ||||
| Closeness | ||||
| Bon Power | Undirected | Less Central Nodes | Any | Any strategy except Listwise Deletion |
| Betweenness | ||||
| Closeness | ||||
| Indegree | Directed | Central Nodes | Any | Probabilistic |
| Indegree | Directed | Less Central Nodes | Any | Probabilistic, Listwise Deletion or Asymmetric |
| Total Degree | Directed | Any | Any | Asymmetric or Probabilistic |
| Bon Power | Directed | Any | Any | Probabilistic, Symmetric or Asymmetric |
| Closeness | Directed | Any | Any | Model-Based |
| Betweenness | Directed | Any | Any | Probabilistic |
Notes.
The model-based approach is assumed to correspond to complex or simple unless explicitly noted.
