NIMBLE: A new way to do MCMC (and more) from BUGS code in R


Interesante … escribir BUGS pero sin utilizar BUGS…

====================================================================================================================

Write statistical models in the BUGS language from R

NIMBLE adopts and extends BUGS as a modeling language and lets you program with the models you create.

Other packages that use the BUGS language are only for Markov chain Monte Carlo (MCMC). With NIMBLE, you can turn BUGS code into model objects and use them for whatever algorithm you want. That includes algorithms provided with NIMBLE and algorithms you write using nimbleFunctions. NIMBLE extends BUGS by allowing multiple parameterizations for distributions, user-written functions and distributions, and more.

Introducing Microsoft R Open


Microsoft poco a poco se va introduciendo en el mundo del R, primero compró Revolutions-Analytics; y ahora ya ofrecve un R server… pues lo último ha sido que RStudio tambien se puede conectar a este server y trabajar contra el.

Introducing Microsoft R Open: Replay and slides

We had a fantastic turnout to last week’s webinar, Introduction to Microsoft R Open. If you missed it, you can watch the replay below. In the talk, I gives some background on the R language and its applications, describe the performance and reproducibility benefits of Microsoft R Open, and give a demonstration of the basics of the R language along with a more in-depth demo of producing a beautiful weather data chart with R.

11th International Workshop on Objective Bayes Methodology. O-Bayes15



The International Workshop on Objective Bayes Methodology, O-Bayes15, will be held in Valencia, Spain, June 1-4, 2015, and June 5 will be devoted to excursions. This will be the 11th meeting of one of the longest running and preeminent meetings in Bayesian statistics, following earlier meetings held in West Lafayette, IN, USA, 1996; Valencia, Spain, 1998; Ixtapa, Mexico, 2000; Granada, Spain, 2002; Aussois, France, 2003; Branson, MO, USA, 2005; Roma, Italy, 2007; Philadelphia, PA, USA, 2009; Shanghai, China, 2011; and Durham, NC, USA 2013. The principal objectives of O-Bayes15 will be to facilitate the exchange of recent research developments in objective Bayes theory, methodology and applications, and related topics, to provide opportunities for new researchers, and to establish new collaborations and partnerships.

Returning to Valencia, O-Bayes15 will be dedicated to Susie Bayarri, to celebrate her life and contributions to Bayesian Statistics. O-Bayes15 will feature 21 invited talks and discussants, 3 tutorials and a poster session. More details will come in this web site soon.
