posterior_interval.brmsfit: Compute posterior uncertainty intervals

In brms: Bayesian Regression Models using 'Stan'

Compute posterior uncertainty intervals

Description

Compute posterior uncertainty intervals for brmsfit objects.

Usage

## S3 method for class '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.

Value

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

Examples

## Not run: 
fit <- brm(count ~ zAge + zBase * Trt,
           data = epilepsy, family = negbinomial())
posterior_interval(fit)

## End(Not run)
