The Fitch-Margoliash (FM) method seeks to maximize the fit of the observed pairwise distances to a tree by minimizing the squared deviation of all possible observed distances relative to all possible path lengths on the tree (Felsenstein, 1997).

http://cmgm.stanford.edu/phylip/fitch.html WebThe Fitch-Margoliash method uses a weighted least squares method for clustering based on genetic distance. Closely related sequences are given more weight in the tree construction process to correct for the increased inaccuracy in measuring distances between distantly related sequences. The distances used as input to the algorithm must be ...

Webfollowing far more complicated ones: Fitch and Margoliash's method (F-M method) (3), Farris' method (4), and the modified Farris method (Y. Tateno and M. Nei, personal communica-tion). Tateno's (8) simulation study, however, shows that under certain conditions this method has a very low probability of producing the correct tree topology. WebThe procedure for constructing tree topologies is similar to that of the unweighted pair-group method (UPG method) but makes corrections for unequal rates of evolution among lineages. The procedure for estimating branch lengths is the same as that of the Fitch and Margoliash method (F-M method) except that it allows no negative branch lengths.
