The method of generalized least squares provides a flexible method of phylogenetic reconstruction from sequence data, after reducing them to pairwise distances between species, corrected for multiple and back mutation. It gives efficient estimates of the branch lengths of a given tree. It also provides a natural measure of the departure of the observed from(More)
There are many interesting connections between music and mathematics, though these are rarely used when teaching maths in schools. In this paper we look at one example which involves using musical motivations to introduce some mathematical ideas. The aim is to develop a random method for making music which produces pleasant results.
