Basic MCMC and Bayesian statistics in… BASIC!

The BASIC programming language was at one point the most widely spread programming language. Many home computers in the 80s came with BASIC (like the Commodore 64 and the Apple II), and in the 90s both DOS and Windows 95 included a copy of the QBasic...

Statistical Theory is our “Write Once, Run Anywhere”

August 9, 2015
By

Having followed the software industry as a casual bystander, I periodically see the tension flare up between the idea of writing “native apps”, software that is tuned to a particular platform (Windows, Mac, etc.) and more cross-platform apps, which run on many platforms without too much modification. Over the years it has come up in

Monte Carlo and the Holy Grail

On 31 Dec 2010, someone wrote in: A British Bayesian curiosity: Adrian Smith has just been knighted, and so becomes Sir Adrian. He can’t be the first Bayesian knight, as Harold Jeffreys was Sir Harold. I replied by pointing to this discussion from 2008, and adding: Perhaps Spiegelhalter can be knighted next. Or maybe Ripley!

Statistical Theater of the Absurd: “Stat on a Hot Tin Roof”

Memory lane: Did you ever consider how some of the colorful exchanges among better-known names in statistical foundations could be the basis for high literary drama in the form of one-act plays (even if appreciated by only 3-7 people in the world)? (Think of the expressionist exchange between Bohr and Heisenberg in Michael Frayn’s play […]

Tyler McCormick sent along this paper, “Probabilistic Cause-of-death Assignment using Verbal Autopsies,” coauthored with Zehang Li, Clara Calvert, Amelia Crampin, Kathleen Kahn, and Samuel Clark: In areas without complete-coverage civil registration and vital statistics systems there is uncertainty about even the most basic demographic indicators. In such areas the majority of deaths occur outside hospitals […] The post Classifying causes of death using “verbal autopsies” appeared first on Statistical Modeling,…
