Comparison of methods for estimating the nucleotide substitution matrix

Oscamou, Maribeth; McDonald, Daniel; Yap, Von Bing; Lladser, Manuel E; Knight, Rob; Huttley, Gavin Austin


BACKGROUND: The nucleotide substitution rate matrix is a key parameter of molecular evolution. Several methods for inferring this parameter have been proposed, with different mathematical bases. These methods include counting sequence differences and taking the log of the resulting probability matrices, methods based on Markov triples, and maximum likelihood methods that infer the substitution probabilities that lead to the most likely model of evolution. However, the speed and accuracy of...[Show more]
