Description

Abstract: Bayesian Discrete phylogeography considers the sampling location of each taxon as fixed to a single or small number of locations without observation error (i.e. uncertainty). In this work, we relaxed this strong assumption and allow for analytic integration of observation error to evaluate the likelihood of the spatial process. We evaluate the use of observation error against more traditional approaches for studying the ancestral state reconstruction of a virus along a phylogeny.
