Table 1. Interpretation of the silhouette values for partitioning methods.
Silhouette coefficient | Proposed interpretation |
---|---|
0.71–1.00 | A strong cluster has been found |
0.51–0.70 | A reasonable cluster has been found |
0.26–0.50 | The cluster is weak and could be artificial |
≤ 0.25 | No substantial cluster has been found |
