Specify a branch length (random) effect for a Brownian motion model

bre_brownian.Rd

This function is meant to be called only in the formula argument of fibre().

Usage

bre_brownian(
  phyf,
  hyper = list(prec = list(prior = "pc.prec", param = c(1, 0.1))),
  latent = 0,
  label = NULL,
  standardise = TRUE
)

Arguments

phyf

A pfc column containing the phylogenetic structure

hyper

Hyper parameters as a list. Specify the prior distribution for engine = INLA models here. Default is a penalised complexity prior with 10% prior probability density greater than 1, which tend to work well for standardised Gaussian responses and Binomial responses.

latent

How many latent variables to generate in engine = INLA models. Default is none.

label

An optional label used to identify the random effect later The default is a label generated from the expression in phyf

standardise

Should the pfc object be standardised based on it's implied typical variance for terminal nodes? Default: TRUE. This helps random effects to be comparable to each other.

Value

A list of data to be used by the model.
