R: Compute posterior uncertainty intervals

posterior_interval.brmsfit {brms} | R Documentation

## 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)
