"WebTo carry out the test, fit the same data with both Fitch and Kitsch, and record the two sums of squares. If the topology has turned out the same, we have N = n (n-1)/2 distances which have been fit with 2n-3 parameters in Fitch, and with n-1 parameters in Kitsch. Then the difference between S (K) and S (F) has d1 = n-2 degrees of freedom. " - Fitch-margoliash算法

This paper focuses on distance based methods. The paper starts with some preliminary knowledge and deﬁnitions in the area, including ﬁnite directed graphs, directed trees and matrices.

Distance-matrix methods of phylogenetic analysis explicitly rely on a measure of "genetic distance" between the sequences being classified, and therefore they require an MSA (multiple sequence alignment) as an input. 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 ea… WebJan 19, 2024 · The Fitch-Margoliash method may be extended from three sequences as shown in example 1 by following the steps shown in the box below, Steps in Fitch …
