For any given tree topology it is possible to solve for the branch lengths that minimize . Q. by standard least squares methods. WebFitch-Margoliash (FM). 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).
WebEmanuel Margoliash (February 10, 1920 – April 10, 2008) was a biochemist who spent much of his career studying the protein cytochrome c. He is best known for his work on molecular evolution ; with Walter Fitch , he devised the Fitch-Margoliash method for constructing evolutionary trees based on protein sequences .
