brmsfit-class

Class brmsfit of fitted mixed-effect models

Models fitted with the brms package are represented as a brmsfit object, which contains the posterior samples, the model code, the relevant data, the model formula, and some other useful information.

Details

Currently, the following S3 methods are available for class brmsfit: as.mcmc, coef, family, fitted, fixef, formula, hypothesis, launch_shiny, logLik, LOO, marginal_effects, model.frame, ngrps, nobs, pairs, parnames, plot, posterior_samples, predict, print, prior_samples, ranef, residuals, stancode, standata, stanplot, summary, update, VarCorr, vcov, WAIC. brmsfit objects do not have their own tidy method yet, but you may use broom::tidyMCMC($fit) to apply the tidy method for stanfit objects.
