WebFitch-Margoliash (FM) and Minimum Evolution (ME) Methods Fitch and Margoliash proposed in 1967 a criteria (FM Method) for fitting trees to distance matrices [2]. This method seeks the least squared fit of all observed pair-wise distances to the expected distance of a tree. The ME method also seeks the tree with the minimum sum of WebJan 19, 2024 · The Fitch and Margoliash (1987) method uses a distance table illustrated in Figure 6.11C.

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). WebFor the Fitch- Margoliash method, which is the default method with this program, P is 2.0. For the Cavalli-Sforza and Edwards least squares method it should be set to 0 (so that the denominator is always 1). An intermediate method is also available in which P is 1.0, and any other value of P, such as 4.0 or -2.3, can also be used.
