ComputeDimensionlessFit

Function ComputeDimensionlessFit - dimensionless fitting of a distance tree

Calling Sequence  ComputeDimensionlessFit(t,Dist,Var)
Parameters
NameTypeDescription

t Treethe given tree
t matrix(numeric)alternatively, the distances over the tree
Dist matrix(numeric)distance matrix
Var matrix(numeric)variances of the distances
Return Type  nonnegative
Synopsis This function computes the Dimensionless fitting index of a set of distances over a tree as in "A Dimensionless Fit Measure for Phylogenetic Distance Trees", J Bioinform Comput Biol, vol 3, pp 1429-1440. Trees built over the same set of species, even with radically different methods, can be ranked by the quality of their fit with this index. The input can be a tree (which is converted to an actual distance matrix with the Tree_matrix) or an actual distance matrix. The input matrices Dist and Var are the distance measured between the species and their variance.
