What is the difference between WinBUGS and OpenBUGS?
OpenBUGS looks very similar to WinBUGS, and is just as stable and reliable, having been validated on a wide range of examples. However OpenBUGS has more advanced functionality for MCMC sampling, and unlike WinBUGS, runs natively on Linux as a command-line program.
How do I use OpenBUGS in R?
Details
- 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 .
How do I run codes in WinBUGS?
Click: File -> Open in the WinBUGS menus. Navigate to your text file containing the WinBUGS code and select and open it. A window with the code should pop up within WinBUGS.
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?

What is Rjags?
The rjags package provides an interface from R to the JAGS library for Bayesian data analysis. JAGS uses Markov Chain Monte Carlo (MCMC) to generate a sequence of dependent samples from the posterior distribution of the parameters. Details. JAGS is a clone of BUGS (Bayesian analysis Using Gibbs Sampling).
Is Stan fast?
The scenario with weak posterior correlations offers ideal conditions, and when JAGS is given a fully conjugate hierarchical model, it is sampling very fast here – showing the fastest performance in this test. Stan is also fast in this situation, but does take about 3 times as long JAGS.
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.
