Introduction

• In the BEAST software package, there are many models of changing effective population size that can be fitted
• Parametric models
  • Exponential growth
  • Logistic growth
• Nonparametric models
  • 'Skyline', 'skyride' models

Fitting models to a single tree

• We will fit a model to a single tree
  • Tree from chronos/LSD
  • One of the trees from a MrBayes run
• This is a fast, exploratory procedure
