## How do I use WinBUGS software?

Installing WinBUGS 1.4 in Windows

- Exit all other programs currently running (particularly if using Windows XP)
- Copy WinBUGS14.exe to your computer.
- Go into Explore and double click on WinBUGS14.exe.
- Follow the instructions in the dialog box.
- You should have a new directory called WinBUGS14 within Program Files.

**What are WinBUGS for?**

WinBUGS is a Bayesian analysis software that uses Markov Chain Monte Carlo (MCMC) to fit statistical models. WinBUGS can be used in statistical problems as simple as estimating means and variances or as complicated as fitting multilevel models, measurement error models, and missing data models.

**How do I install WinBUGS?**

How to Obtain WinBugs (it’s free!)

- Open your favorite web browser, and go to the BUGS website:
- Click on the ‘WinBUGS’ link (4th link down on the left), and read the page.
- Click on the ‘Obtaining the File’ link or scroll down to the ‘Obtaining the File’ section.
- �Click on ‘WinBUGS14.exe’ to save to your computer.

### How do you reference WinBUGS?

Note: The preferred reference for citing WinBUGS in scientific papers is: Lunn, D.J., Thomas, A., Best, N., and Spiegelhalter, D….WinBUGS 1.4. 3

- Features a graphical user interface and on-line monitoring and convergence diagnostics.
- Over 30000 downloads, and a huge number of applications and links.

**Is Stan better than Jags?**

The models differ in terms of pooling, conjugacy, and centered parameter specifications. The results are roughly as expected: JAGS exhibits both blazing fast and incredibly slow sampling, while Stan delivers somewhat more stable performance, being relatively efficient also in harder scenarios.

**How do I use WinBUGS in R?**

To run WinBugs from R

- Write a Bugs model in a file with a .
- Prepare the inputs to the “bugs” function and run it (see example below).
- A WinBugs14 window will pop up and R will freeze up.
- If an error message appears, re-run with the debug=TRUE option.

#### What is Bayesian analysis and its purpose?

Bayesian analysis, a method of statistical inference (named for English mathematician Thomas Bayes) that allows one to combine prior information about a population parameter with evidence from information contained in a sample to guide the statistical inference process.

**How do I install WinBUGS on my Mac?**

OpenBUGS

- Install Homebrew.
- Open the terminal on your Mac and type: brew install wine.
- Download the setup program for OpenBUGS on Windows from here (current version: OpenBUGS323setup.exe).
- Still in Terminal, navigate to the directory where the setup program was downloaded.

**How do I run an Openbug in R?**

To run:

- Write a BUGS model in an ASCII file (hint: use write. model ).
- Go into R.
- Prepare the inputs for the bugs function and run it (see Example section).
- An OpenBUGS window will pop up and R will freeze up. The model will now run in OpenBUGS. It might take awhile.
- If an error message appears, re-run with debug=TRUE .

## What is Jags and Stan?

JAGS is a variation on BUGS, similar to WinBUGS and OpenBUGS, where a model states just relations between variables. Stan on the other hand, is a program where a model has clearly defined parts, where order of statements is of influence. Stan is compiled, which takes some time by itself.

**What is WinBUGS language?**

WinBUGS Language 4.1. Introduction: What is WinBUGS BUGS: Bayesian inference Using Gibbs Sampling Computing Language for definition of the Model (likelihood, prior) Computes the full Conditional Distributions and generates samples from the posterior distribution of interest

**What are the best Bayesian analysis programs?**

Stan is another program for general Bayesian analysis, developed even more recently at Columbia University. It uses a modelling language inspired by BUGS and superficially similar, but it is conceptually different in many ways.

### What is the WinBUGS syntax list?
