NJ: Neighbor-Joining in phangorn: Phylogenetic Reconstruction …

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 other means of analysis (e.g. maximum parsimony, maximum likelihood) may be computationally prohibitive. Neighbor joining has the property that if the input distance matrix is correct, then the output tree … WebApr 26, 2013 · Comparing Neighbor joining vs Maximum Liklihood phylogenetic tree reconstruction, using the general time reversible model of nucleotide evolution for both, plus a gamma factor for different rates of evolution at different sites, plus allowing a percentage of sites to be held as invariable.

WebWe have developed a phylogenetic tree reconstruction method that detects and reports multiple, topologically distant, low cost solutions. Our method is a generalization of the … WebThe most popular among them are the Neighbor Joining (NJ) [8] and UPGMA [9]. The NJ can be seen as a classic algorithm in the field of tree reconstruction, as it is one of the most frequently used techniques [10].
