logL.joint.OU.BM

Returns log-likelihood for an Ornstein-Uhlenbeck model where the optimum evolves as a Unbiased Random Walk. The movement of the optimum is not parameterized based on separate data.

Facilitates univariate and multivariate analysis of evolutionary sequences of phenotypic change. The package extends the modeling framework available in the 'paleoTS' package. Please see <https://klvoje.github.io/evoTS/index.html> for information about the package and the implemented models.
