Many biological characteristics of evolutionary inter-est are not scalar variables but continuous functions.Here we use phylogenetic Gaussian process regres-sion to model the evolution of simulated fu...
A simple and numerical stable algorithm for solving the cone projection problem based on a Gram-Schmidt process
