WebFor Bayesian models from packages rstanarm or brms , models will be "converted" to their frequentist counterpart, using bayestestR::bayesian_as_frequentist . A more advanced model-check for Bayesian models will be implemented at a later stage. Note This function just prepares the data for plotting. To create the plots, see needs to be installed. WebAbstract The brms package allows R users to easily specify a wide range of Bayesian single-level and multilevel models which are fit with the probabilistic programming language Stan behind the scenes. Several response distributions are supported, of which all parameters (e.g., location, scale, and shape) can be predicted.
