Compute posterior uncertainty intervals — posterior

Compute posterior uncertainty intervals for brmsfit objects.

# S3 method for brmsfit
posterior_interval(object, pars = NA, variable = NULL, prob = 0.95, ...)

Arguments

object: An object of class brmsfit.
pars: Deprecated alias of variable. For reasons of backwards compatibility, pars is interpreted as a vector of regular expressions by default unless fixed = TRUE is specified.
variable: A character vector providing the variables to extract. By default, all variables are extracted.
prob: A value between 0 and 1 indicating the desired probability to be covered by the uncertainty intervals. The default is 0.95.
...: More arguments passed to as.matrix.brmsfit.

A matrix with lower and upper interval bounds as columns and as many rows as selected variables.
