Simulation of observed phylogeny given a dated tree
simobsphy(tree, mu = 10, sigma = 10, model = "strictgamma")
Dated tree
Substitution clock rate
Per-branch std on the clock rate (used only by relaxed gamma model and negbin model)
Which model to use (poisson or negbin or strictgamma or relaxedgamma or arc or carc)
