rstanarm

This is an R package that emulates other R model-fitting functions but uses Stan (via the rstan package) for the back-end estimation. The primary target audience is people who would be open to Bayesian inference if using Bayesian software were easier but would use frequentist software otherwise.

Installation

Latest Release

The most recent rstanarm release can be installed from CRAN via

install.packages("rstanarm")

Development Version

To install from GitHub, first make sure that you can install the rstan package and C++ toolchain by following these instructions. Once rstan is successfully installed, you can install rstanarm from GitHub using the devtools package by executing the following in R:

if (!require(devtools)) {
  install.packages("devtools")
  library(devtools)
}
install_github("stan-dev/rstanarm", build_vignettes = FALSE)

You can switch build_vignettes to TRUE but it takes a lot longer to install and the vignettes are already separately available from the Stan website and CRAN. If installation fails, please let us know by filing an issue.
