Quinn email: jongheepark@snu.ac.kr version: 2023-07-17 source: https://github.com/cran-task-views/Bayesian/ --- ## CRAN Task View: Bayesian Inference Applied researchers interested in Bayesian statistics are increasingly attracted to R because of the ease of which one can code algorithms to sample from posterior distributions as well as the significant number of packages contributed to the Comprehensive R Archive Network (CRAN) that provide tools for Bayesian inference. This task view catalogs these tools. In this task view, we divide those packages into four groups based on the scope and focus of the packages. We first review R packages that provide Bayesian estimation tools for a wide range of models. We then discuss packages that address specific Bayesian models or specialized methods in Bayesian statistics. This is followed by a description of packages used for post-estimation analysis. Finally, we review packages that link R to other Bayesian sampling engines such as [JAGS](http://mcmc-jags.sourceforge.net/), [OpenBUGS](http://www.openbugs.net/), [WinBUGS](http://www.mrc-bsu.cam.ac.uk/software/bugs/), [Stan](http://mc-stan.org/), and [TensorFlow](https://www.tensorflow.org). ### General Purpose Model-Fitting Packages - The `r pkg("arm", priority = "core")` package contains R functions for Bayesian inference using lm, glm, mer and polr objects. - `r pkg("BACCO", priority = "core")` is an R bundle for Bayesian analysis of random functions. `r pkg("BACCO")` contains three sub-packages: emulator, calibrator, and approximator, that perform Bayesian emulation and calibration of computer programs. - `r pkg("bayesforecast", priority = "core")` provides various functions for Bayesian time series analysis using 'Stan' for full Bayesian inference.

It imports draws from BUGS format, or from plain matrices. `r pkg("boa")` provides the Gelman and Rubin, Geweke, Heidelberger and Welch, and Raftery and Lewis diagnostics, the Brooks and Gelman multivariate shrink factors. - The `r pkg("coda", priority = "core")` (Convergence Diagnosis and Output Analysis) package is a suite of functions that can be used to summarize, plot, and and diagnose convergence from MCMC samples. `r pkg("coda")` also defines an `mcmc` object and related methods which are used by other packages. It can easily import MCMC output from WinBUGS, OpenBUGS, and JAGS, or from plain matrices. `r pkg("coda")` contains the Gelman and Rubin, Geweke, Heidelberger and Welch, and Raftery and Lewis diagnostics. - `r pkg("plotMCMC")` extends `r pkg("coda")` by adding convenience functions to make it easier to create multipanel plots. The graphical parameters have sensible defaults and are easy to modify via top-level arguments. - `r pkg("ramps")` implements Bayesian geostatistical analysis of Gaussian processes using a reparameterized and marginalized posterior sampling algorithm. ### Packages for learning Bayesian statistics - `r pkg("BaM")` provide functions and datasets for "Bayesian Methods: A Social and Behavioral Sciences Approach" by Jeff Gill (Chapman and Hall/CRC, 2002/2007/2014). - `r pkg("BayesDA")` provides R functions and datasets for "Bayesian Data Analysis, Second Edition" (CRC Press, 2003) by Andrew Gelman, John B. Carlin, Hal S. Stern, and Donald B. Rubin. - The `r pkg("Bolstad")` package contains a set of R functions and data sets for the book Introduction to Bayesian Statistics, by Bolstad, W.M. (2007). - The `r pkg("LearnBayes")` package contains a collection of functions helpful in learning the basic tenets of Bayesian statistical inference. It contains functions for summarizing basic one and two parameter posterior distributions and predictive distributions and MCMC algorithms for summarizing posterior distributions defined by the user. It also contains functions for regression models, hierarchical models, Bayesian tests, and illustrations of Gibbs sampling. ### Packages that link R to other sampling engines - `r pkg("bayesmix")` is an R package to fit Bayesian mixture models using [JAGS](http://mcmc-jags.sourceforge.net/). - `r pkg("BayesX")` provides functionality for exploring and visualizing estimation results obtained with the software package [BayesX](http://www.BayesX.org/). - `r pkg("Boom")` provides a C++ library for Bayesian modeling, with an emphasis on Markov chain Monte Carlo. - **BRugs** provides an R interface to [OpenBUGS](http://www.openbugs.net/). It works under Windows and Linux. **BRugs** used to be available from CRAN, now it is located at the [CRANextras](http://www.stats.ox.ac.uk/pub/RWin/) repository. - `r pkg("brms")` implements Bayesian multilevel models in R using [Stan](http://mc-stan.org/). A wide range of distributions and link functions are supported, allowing users to fit linear, robust linear, binomial, Poisson, survival, response times, ordinal, quantile, zero-inflated, hurdle, and even non-linear models all in a multilevel context. `r pkg("shinybrms")` is a graphical user interface (GUI) for fitting Bayesian regression models using the package `r pkg("brms")`. - `r pkg("greta")` allows users to write statistical models in R and fit them by MCMC and optimisation on CPUs and GPUs, using Google **'TensorFlow'** . `r pkg("greta")` lets you write your own model like in BUGS, JAGS and Stan, except that you write models right in R, it scales well to massive datasets, and it is easy to extend and build on. - There are two packages that can be used to interface R with [WinBUGS](http://www.mrc-bsu.cam.ac.uk/software/bugs/). `r pkg("R2WinBUGS")` provides a set of functions to call WinBUGS on a Windows system and a Linux system. - There are three packages that provide R interface with [Just Another Gibbs Sampler (JAGS)](http://mcmc-jags.sourceforge.net/) : `r pkg("rjags")`, `r pkg("R2jags")`, and `r pkg("runjags")`. - All of these BUGS engines use graphical models for model specification. As such, the `r view("GraphicalModels")` task view may be of interest. - `r pkg("rstan")` provides R functions to parse, compile, test, estimate, and analyze Stan models by accessing the header-only Stan library provided by the `StanHeaders' package. The [Stan](http://mc-stan.org/) project develops a probabilistic programming language that implements full Bayesian statistical inference via MCMC and (optionally penalized) maximum likelihood estimation via optimization. - `r pkg("rstanarm")` estimates previously compiled regression models using the `r pkg("rstan")` package, which provides the R interface to the Stan C++ library for Bayesian estimation. - `r pkg("pcFactorStan")` provides convenience functions and pre-programmed Stan models related to the paired comparison factor model. Its purpose is to make fitting paired comparison data using Stan easy. The Bayesian Inference Task View is written by Jong Hee Park (Seoul National University, South Korea), Andrew D. Martin (Washington University in St. Louis, MO, USA), and Kevin M. Quinn (UC Berkeley, Berkeley, CA, USA).
