RStanArm

Bayesian applied regression modeling via Stan

RStanArm allows users to specify models via the customary R commands, where

  • models are specified with formula syntax,

  • data is provided as a data frame, and

  • additional arguments are available to specify priors.

Estimation may be carried out with Markov chain Monte Carlo, variational inference, or optimization (Laplace approximation). Graphical posterior predictive checking, leave-one-out cross-validation, and posterior visualization are tightly integrated.
