WebThe DistanceTreeConstructor has two algorithms: UPGMA (Unweighted Pair Group Method with Arithmetic Mean) and NJ (Neighbor Joining). Both algorithms construct trees based on a distance matrix. So before using … 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.
