Web28 jan. 2024 · Recall that the goal here is not to study EVT, but just use it for Bayesian inference. We will use the evd package with the dgev() family of functions (rgev(), pgev(), as well as the ggplot2 and gridExtra packages for visualization. When the shape parameter is set to “0” for the GEV distribution, you retrieve the Gumbel distribution. WebMrBayes is a program for Bayesian inference and model choice across a wide range of phylogenetic and evolutionary models.
