brmsfit-class {brms} | R Documentation

## Class `brmsfit` of models fitted with the brms package

### Description

Models fitted with the `brms` package are represented as a `brmsfit` object, which contains the posterior draws (samples), model formula, Stan code, relevant data, and other information.

### Details

See `methods(class = "brmsfit")` for an overview of available methods.
