Class brmsfit of models fitted with the brms package

Source: R/brmsfit-class.R

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.

Slots

formula

A brmsformula object.

data

A data.frame containing all variables used in the model.

data2

A list of data objects which cannot be passed via data.

prior

A brmsprior object containing information on the priors used in the model.

stanvars

stan_args

Named list of additional control arguments that were passed to the Stan backend directly.

fit
