SLOUCH: Stochastic Linear Ornstein Uhlenbeck Comparative Hypotheses
Function to fit Ornstein-Uhlenbeck models of trait evolution
Model Summary
An implementation of a phylogenetic comparative method. It can fit univariate among-species Ornstein-Uhlenbeck models of phenotypic trait evolution, where the trait evolves towards a primary optimum. The optimum can be modelled as a single parameter, as multiple discrete regimes on the phylogenetic tree, and/or with continuous covariates.
