Neighbor-joining tree
In bioinformatics, neighbor joining is a bottom-up (agglomerative) clustering method for the creation of phylogenetic trees, created by Naruya Saitou and Masatoshi Nei in 1987. Usually based on DNA or protein sequence data, the algorithm requires knowledge of the distance between each pair of taxa … See more Neighbor joining takes a distance matrix, which specifies the distance between each pair of taxa, as input. The algorithm starts with a completely unresolved tree, whose topology corresponds to that of a star network, … See more Let us assume that we have five taxa $${\displaystyle (a,b,c,d,e)}$$ and the following distance matrix $${\displaystyle D}$$: First step First joining We calculate the See more The main virtue of NJ is that it is fast as compared to least squares, maximum parsimony and maximum likelihood methods. This makes it practical for analyzing large data sets (hundreds or thousands of taxa) and for bootstrapping, for which purposes … See more • The Neighbor-Joining Method — a tutorial See more Neighbor joining may be viewed as a greedy heuristic for the Balanced Minimum Evolution (BME) criterion. For each topology, BME defines the tree length (sum of branch lengths) to be a particular weighted sum of the distances in the distance matrix, … See more There are many programs available implementing neighbor joining.
