Utility of each data partition to tree resolution
|
Does the strength of the signal decay for each partition as branch lengths increase?
|
No relationship between frequency of CI1 characters and branch length
|
Linear regression
|
| |
Is there variation in the contribution of data partitions to node support relative to branch length?
|
Equal frequency of CI1 characters for each data partition across branch lengths
|
Chi-square
|
| |
Is there variation in relative support a partition contributes to short and long branches?
|
Uniform proportion of CI1 for each data partition across branch lengths
|
Kruskal-Walis

|
Utility of 3rd codon positions
|
Are third positions less informative than other codon positions?
|
Uniform frequency of CI1 characters among codon positions
|
Chi-square

Conflict among data partitions in the simultaneous analysis
|
Is there evidence for interaction among data partitions?
|
Even distribution of PBS across node heights
