A Robust ANOVA Approach to Estimating a Phylogeny from Multiple Genes.

abstract：:The relative evolutionary rates at individual sites in proteins are informative measures of conservation or adaptation. Often used as evolutionarily aware conservation scores, relative rates reveal key functional or strongly selected residues. Estimating rates in a phylogenetic context requires specifying a protein su...
