Additive distance

WebJul 27, 2014 · 6 In general what you ask cannot be true: indeed, we know that outer measure is not σ -additive but it is σ -subadditive. If it were finitely additive, it would be σ -additive. Nevertheless, if you ask that the sets have positive distance then the answer becomes affirmative. An additive distance matrix is a special type of matrix used in bioinformatics to build a phylogenetic tree. Let x be the lowest common ancestor between two species i and j, we expect Mij = Mix + Mxj. This is where the additive metric comes from. A distance matrix M for a set of species S is said to be additive if and only if there exists a phylogeny T for S such that:
