We therefore define a likelihood function L(θ) = P[D|θ] (sometimes written as L(θ|D) = P[D|θ]) that captures how 'likely' it is to observe the data for a given value of the parameters θ. A high likelihood indicates a good fit. The maximum likelihood estimate is 1 Page 2 2 CONTENTS the value of θ that maximises L(θ).

These compute the probability of everything at site i at or above node j on the tree, given that node j is in state s. Thus it assumes something.
Therefore, the probability of finding a mutation along one branch in a phylogenetic tree can be calculated by using the same maximum likelihood framework. The ...
