WebThe neighbor-joining method is a special case of the star decomposition method. In contrast to cluster analysis neighbor-joining keeps track of nodes on a tree rather than … WebNeighbor-joining is a well-established hierarchical clustering algorithm for inferring phylogenies. It begins with observed distances between pairs of sequences, and clustering order depends on a metric related to those distances. The canonical algorithm requires O ( n 3) time and O ( n 2) space for n sequences, which precludes application to ...
