Table 1 Interpretation of PAM silhouette widths
From: Cluster analysis of protein array results via similarity of Gene Ontology annotation
Statistic | Value | Interpretation |
|---|---|---|
si | close to 1 | object assigned to correct cluster |
| Â | close to 0 | intermediate object between two clusters |
| Â | close to -1 | misclassified object |
siC | close to 1 | well separated cluster |
| Â | < 0.25 | cluster not well separated from neighbour(s) |
siD | 0.51–1.00 | reasonable to strong clustering structure |
|  | 0.26–0.50 | weak clustering structure, use additional methods |
|  | 0.00–0.25 | no substantial clustering structure |
