slouch (version 2.1.5)

Stochastic Linear Ornstein-Uhlenbeck Comparative Hypotheses

Description

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. See also Hansen (1997) , Butler & King (2004) , Hansen et al. (2008) .
