Maximum Likelihood Estimation for the Offset-Normal Shape Distributions Using EM [PDF]

, 2010
The offset-normal shape distribution is defined as the induced shape distribution of a Gaussian distributed random configuration in the plane. Such distributions were introduced by Dryden and Mardia (1991) and represent an important parameterized family ...

The shape of human gene family phylogenies [PDF]

, 2006
Background: The shape of phylogenetic trees has been used to make inferences about the evolutionary process by comparing the shapes of actual phylogenies with those expected under simple models of the speciation process. Previous studies have focused
