Abstract The brms package implements Bayesian multilevel models in R using the probabilis- tic programming language Stan. of thresholds (i.e. Families beta and dirichlet can be used to model "equidistant" restricts the distance between Also note that in the summary output of brms, coefficients for the log of discrimination just have the prefix disc_, although they are in fact on the log scale. Family objects provide a convenient way to specify the details of the models used by many model fitting functions. "flexible" provides the standard unstructured thresholds, The information contained in this website is not a guarantee of benefits. (see brmsformula for details). The brms package (Bürkner, 2017) is an excellent resource for modellers, providing a high-level R front end to a vast array of model types, all fitted using Stan. The core of models implemented in brms is the prediction of the response y through predicting all parameters qp of the response distribution D, which is also called the model family in many R packages. the auxiliary quantile parameter to the quantile of interest.
