Fitch -- Fitch-Margoliash and Least-Squares Distance Methods

WebJul 31, 2014 · The Fitch-Margoliash algorithm applies a least-squares method to estimate per branch length (in our case, equivalent to the genome multiplicity) based on all pairwise distances between the genomes in comparison. The procedure was pipelined by an in-house Python script with manual inspections at various intermediate stages. Weberror, the assumptions of the Fitch-Margoliash algorithm are approached. It is impossible to decide between the as-sumptions of the Fitch-Margoliash and Cavalli-Sforza and Edwards algorithms without know-ing the true tree topology and branch lengths. Since the two algorithms are limiting cases, nei-ther is likely to be quite correct. One solution north county recreation complex
