Scalable Bayesian divergence time estimation with ratio transformations
Xiang Ji, Alexander A. Fisher, Shuo Su +5
Divergence time estimation is crucial to provide temporal signals for dating biologically important events, from species divergence to viral transmissions in space and time. With t…
Shrinkage-based random local clocks with scalable inference
Alexander A. Fisher, Xiang Ji, Akihiko Nishimura +2
Local clock models propose that the rate of molecular evolution is constant within phylogenetic sub-trees. Current local clock inference procedures scale poorly to large taxa probl…
Relaxed random walks at scale
Alexander A. Fisher, Xiang Ji, Philippe Lemey +1
Relaxed random walk (RRW) models of trait evolution introduce branch-specific rate multipliers to modulate the variance of a standard Brownian diffusion process along a phylogeny a…
