I must confess to feeling an almost obsessive fascination with intransitive games, dice, and other artifacts. The most famous intransitive game is rock, scissors, paper. Rock beats scissors. Scissors beats paper. Paper beats rock. Everyone older than 7 seems to know this, but very few people are aware that dice can exhibit this same behavior,
The standard, textbook way to represent a density function looks like this: Perhaps you have seen this before? (Plot created in R, all source code from this post is included at the end). Not only will you find this plot in statistics books, you’ll also see it in medical texts, sociology, and even economics books.
R did definitely not start to be THE statistical computing tool. The “two Rs” in far down-under just needed some tool which was not too expensive and structured enough to support the elementary statistics classes filled with hundreds of students. Another constraint was the computing lab which was large enough, but “only” filled with Mac
In connection with the Valencia 9 meeting that started yesterday, and with Hedie‘s talk there, we have posted on arXiv a set of comments on particle learning. The arXiv paper contains several discussions but they mostly focus on the inevitable degeneracy that accompanies particle systems. When Lopes et al. state that is not of interest 
There are many reasons to create an R package, such as codes protection, convenient usage, etc. However, creating an R package in Unix is not hard, it IS in Windows, as R is designed in a Unix environment which includes a set of compilers, programming utilities, and text-formatting routines while Windows lacks those. I used to build an R...

Although the revision is quite minor, it took us two months to complete from the time I received the news in the Atlanta airport lounge… The vanilla Rao-Blackwellisation paper with Randal Douc has thus been resubmitted to the Annals of Statistics. And rearXived. The only significant change is the inclusion of two tables detailing computing 
I've released version 0.2-0 of highlight to CRAN This version brings some more additions to the sweave driver that uses highlight to produce nice looking vignettes with color coded R chunks The driver gains new arguments boxes, bg and border to c...
I was reading over at math-blog.com about a concept called numeri ritardatari. This sounds a lot like “retarded numbers” in Italian, but apparently “retarded” here is used in the sense of “late” or “behind” and not in the short bus sense. I barely scanned the page, but I think I got the gist of it:
The version 0.1-8 of highlight introduced a small bug in the latex renderer. This is now fixed in version 0.1-9 and the latex renderer also gains an argument "minipage" which wraps the latex code in a minipage environment. I've used this to make...
Having worked with Unix (BSD, HPUX, IRIX, Linux and OSX), Windows (NT4, 2000, XP, Vista and 7) for quite a while I have seen a lot of different software tools. I would like to quickly exhibit my “must have” list. These are the packages that I find to be the single “must have offerings” in Related posts:
