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.

100315 Programa CIO

Dirigido por Sergi Escrivá. Dedicado a la actualidad del Instituto Centro de Investigación Operativa (CIO) de la Universidad Miguel Hernández de Elche.

En el programa de hoy hemos entrevistado a Xavi Barber, investigador del CIO y licenciado en Ciencias y Técnicas Estadísiticas por la Universidad Miguel Hernández de Elche y Doctorado en Estadística e Investigación. Debido al auge de Internet y las nuevas tecnologías,  hoy en día resulta imprescindible gestionar grandes cantidades de datos. Para ello nació el término inglés Big Data. A ese concepto está dedicado el programa de hoy.

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.

7 blogs sobre predicción


(This article was first published on Hyndsight » R, and kindly contributed to R-bloggers)

There are several other blogs on forecasting that readers might be interested in. Here are seven worth following:

  1. No Hesitations by Francis Diebold (Professor of Economics, University of Pennsylvania). Diebold needs no introduction to forecasters. He primarily covers forecasting in economics and finance, but also xkcd cartoons, graphics, research issues, etc.
  2. Econometrics Beat by Dave Giles. Dave is a professor of economics at the University of Victoria (Canada), formerly from my own department at Monash University (Australia), and a native New Zealander. Not a lot on forecasting, but plenty of interesting posts about econometrics and statistics more generally.
  3. Business forecasting by Clive Jones (a professional forecaster based in Colorado, USA). Originally about sales and new product forecasting, but he now covers a lot of other forecasting topics and has an interesting practitioner perspective.
  4. Freakonometrics: by Arthur Charpentier (an actuary and professor of mathematics at the University of Quebec at Montreal, Canada). This is the most prolific blog on this list. Wide ranging and taking in statistics, forecasting, econometrics, actuarial science, R, and anything else that takes his fancy. Sometimes in French.
  5. No free hunch: the kaggle blog. Some of the most interesting posts are from kaggle competition winners explaining their methods.
  6. Energy forecasting by Tao Hong (formerly an energy forecaster for SAS, now a professor at UNC). He covers mostly energy forecasting issues and job postings.
  7. The official IIF blog. Conferences, jobs, member profiles, etc.
