6 Phylogenetic tree construction based on the minimum variance reduction.
13 \item{X}{a distance matrix.}
14 \item{V}{a variance matrix.}
15 \item{fs}{agglomeration criterion parameter.}
18 The MVR method can be seen as a version of BIONJ which is not
19 restricted to the Poison model of variance (Gascuel 2000).
