The R package, rube is a Really Useful WinBUGS (or JAGS) Enhancer. It makes working with WinBUGS much easier. It is (currently) built on top of the R2WinBUGS package. It works with either the WinBUGS or the JAGS MCMC engines. The latter requires the R2jags package. R2WinBUGS or R2jags takes a good rst step to allow you to. · It is a program for analysis of Bayesian hierarchical models using Markov Chain Monte Carlo (MCMC) simulation not wholly unlike BUGS. JAGS was written with three aims in mind: To have a cross-platform engine for the BUGS language. To be extensible, allowing users to write their own functions, distributions and samplers.

Additionally, you can define further aspects of the MCMC algorithm of repeated sampling. By specifying the number of iterations, you define how many samples should be taken from the posterior distribution overall. Run the JAGS model. The txt. file holds the Bugs model input (excluding data and inits parts). Data is a list of the vectors you. If JAGS is installed, you will receive the following message: Welcome to JAGS on Tue Dec 23 JAGS is free software and comes with ABSOLUTELY NO WARRANTY. For instructions on downloading JAGS, see the home page at www.doorway.ru To fully understand how JAGS works, you need to read the JAGS User Manual. The manual explains the basics of modelling with JAGS and shows the functions and distributions available in the dialect of the BUGS language used by JAGS.
What is JAGS? JAGS stands for Just Another Gibbs Sampler. To quote the program author, Martyn Plummer, “It is a program for analysis of Bayesian hierarchical models using Markov Chain Monte Carlo (MCMC) simulation ” It uses a dialect of the BUGS language, similar but a little different to OpenBUGS and WinBUGS. 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). See Lunn et al () for. Running a model in JAGS JAGS is designed for inference on Bayesian models using Markov Chain Monte Carlo (MCMC) simulation. Running a model refers to generating samples from the posterior distribution of the model parameters. This takes place in ve steps: 1. De nition of the model 2. Compilation 3. Initialization 4. Adaptation and burn-in 5. Monitoring.
