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. 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 WebDistance matrix methods .

Distance is often defined as the fraction of mismatches at aligned positions, with gaps either ignored or counted as mismatches. Distance methods attempt to construct an all-to-all matrix from the sequence query set describing the distance between each sequence pair. From this is const…
