Cophenetic metrics for phylogenetic trees, after Sokal and Rohlf
Correlation between metrics over phylogenetic trees with 3 leaves
Non-necessary binary phylogenetic trees
Spearman's correlation between cophenetic, nodal and RF metrics.
| | Cophenetic p=1 | Cophenetic p=2 | Nodalsp p=1 | Nodalsp p=2 | RF |
| Coph p=1 | 1.0 | 1.0 | 1.0 | 1.0 | 1.0 |
| Coph p=2 | | 1.0 | 1.0 | 1.0 | 1.0 |
| Nsp p=1 | | | 1.0 | 1.0 | 1.0 |
| Nsp p=2 | | | | 1.0 | 1.0 |
| RF | | | | | 1.0 |
2D histograms. A darker squeare means that there are more trees with that relationship.
