Announcing the first release of the HYDRA Java library for Markov Chain Monte Carlo. HYDRA is an open-source, platform-neutral library for performing Markov Chain Monte Carlo. It implements the logic of standard MCMC samplers within a framework designed to be easy to use and to extend while allowing integration with other software tools. HYDRA provides methods for implementing MCMC samplers using Metropolis, Metropolis-Hastings, Gibbs methods. In addition, it provides classes implementing several unique adaptive and multiple chain/parallel MCMC methods. It was developed as part of my Ph.D. thesis work at the University of Washington. The Hydra package is available from: http://www.warnes.net/Hydra My thesis, which describes one of the adaptive MCMC algorithms and gives an tutorial on constructing MCMC samplers using the HYDRA library is available at http://www.warnes.net/MCMC -Greg Warnes <greg at warnes.net> -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-announce mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
