La Défense, Paris, Feb. 04, 2013Deliverance!!! We have at last completed our book! Bayesian Essentials with R is off my desk! In a final nitty-gritty day of compiling and recompiling the R package bayess and the LaTeX file, we have reached versions that were in par with our expectations. The package has been submitted to CRAN (it has gone back and forth a few times, with requests to lower the computing time in the examples: each example should take less than 10s, then 5s…), then accepted by CRAN, incl. a Windows version, and the book has be sent to Springer-Verlag. This truly is a deliverance for me as this book project has been on my work horizon almost constantly for more than the past two years, led to exciting times in Luminy, Carnon and Berlin, has taken an heavy toll on my collaborations and research activities, and was slowly turning into a unsavoury chore! I am thus delighted Jean-Michel and I managed to close the door before any disastrous consequence on either the book or our friendship could develop. Bayesian Essentials with R is certainly an improvement compared with Bayesian Core, primarily by providing a direct access to the R code. We dearly hope it will attract a wider readership by reducing the mathematical requirements (even though some parts are still too involved for most undergraduates) and we will keep testing it with our own students in Montpellier and Paris over the coming months. In the meanwhile, I just enjoy this feeling of renewed freedom!!!

author rank

Posted in Statistics with tags , , , , , on October 11, 2012 by xi'an

Got the following email from Amazon:

Today we have added a new feature, Amazon Author Rank, the definitive list of best-selling authors on Amazon.com. This list makes it easy for readers to discover the best-selling authors on Amazon.com overall and within a selection of major genres. Your Amazon Author Rank is 44,881 in Print Books.

It is a new feature so, with a very limited past horizon, this rank seems to be moving wildly! (For instance, it is now 36,776, just a few hours later.) But so are the individual book sales. Hence a clear lack of smoothing in the indicator.

Another interesting feature of this Author Central facility is the display of US sales by district, Not only because it shows that New York and San Francisco are the cities where I sell the most books (great!) but also because it uses the notion of “combined areas”, aggregating “the copies sold in these sparsely populated areas in order to obscure any single retailer’s sales”. A good display of data protection (even though the level of aggregation sounds too high to me, resulting in “combined areas” being the 3rd highest sale area. And including Gainesville, Florida and Ithaca, New York, the two latest locations of George Casella, in this combination!

You’re “Culture Curious”

Posted in Books, Kids, pictures, Travel with tags , , on November 13, 2011 by xi'an

The New York Times has a personality quiz: one has to click on a favourite picture and the computer delivers a complete personality sketch… Here is mine’s , very very much off-the-mark!

   

   

You’re Culture Curious

Modern in your thinking [not!] and fun loving in your outlook on life [not!], you are on the pulse of what’s hot [not!], and you are not afraid to push the boundaries in the name of style and creativity [not!]. Moving forward with the times is what’s important to you [not!]. You are a true optimist at heart [not!not!not!]. You like to see the world through rose-tinted spectacles [not!]. It’s all about believing that dreams can come true [not!].

You’re sophisticated [not!] and inquisitive with a real passion for art and culture. You pride yourself on being an early adopter of the latest music and films [not!] and always like to have a good book on the go. Your ability to bring together very diverse and even dissenting opinions is rooted in your appreciation for all points of view [not!]. You believe in immersing yourself in interesting experiences that make you look at people, places and opportunities from new angles [not always!]. Being sensitive and creative you want to feel connected to the world around you [not!] and actively seek out opportunities to explore it [not everywhere!]. It’s all about broadening your horizons and living life to the full [not!]. Anything else would not fulfill your curious nature [not!]. You’ll love the list of The Best 1,000 Movies Ever Made, the Critics’ Picks and Arts Beat [not!].

Then my daughter took it with the following [less off-the-mark?] result [despite sharing some common pictures]:

You’re a Life Lover

You are very open-minded and ready to embrace new ideas and fresh ways of thinking [not!]. Despite being down-to-earth and easy-going [not!], you have a quirky, whimsical side to you that sometimes takes people by surprise. When all is said and done, you are a bit of an intellect with a tendency to do a spot of soul searching from time to time.

You’re creative and imaginative and like to be inspired. Home is where your heart is and you love nothing more than putting personal touches to your space. You’re laid-back and relaxed [not!] with a very healthy attitude to life. Naturally down-to-earth, you don’t believe in sweating the small stuff. Life’s for living, with minimum stress [not!] and maximum enjoyment and so fun with family and friends is top of the list as far as you’re concerned. Food is a definite passion too [not!] and you’re always up for tantalizing your taste buds [not!]. You’re a bit of a dreamer at heart. But there’s nothing wrong with that. Set your sights high and you’ll create the life you deserve. The Home and Garden section is perfect for you – bring the latest trends into your home [not!].

National Gallery of Ireland

Posted in pictures, R, Travel with tags , , , , , , , on October 16, 2011 by xi'an

During a short if profitable visit to Dublin for a SFI meeting on Tuesday/Friday, I had the opportunity to visit the National Gallery of Ireland in my sole hour of free time (as my classy hotel was very close). The building itself is quite nice, being well-inserted between brick houses from the outside, while providing impressive height, space, and light from the inside.

The masterpiece gallery is quite small (unless I missed a floor!), if filled with masterpieces like a painting by Caillebotte I did not know.

 

The modern art gallery was taken by a temporary (and poorly exposed) exhibit that includes live happenings (five persons wearing monkish outfits standing around a mommy floating in mid-air), tags (!), and two interesting pieces: one was made of several tables filed with piles of books glued together and sculpted, giving an output that looked like 2-D histograms, and reminding me of the fear histograms discussed on  Statisfaction by Julyan a few days ago. (Note the Mathematica book in the last picture!) While I love books very much, I am also quite interested in sculptures involving books, like the one I saw a few years ago where the artist had grown different cereals on opened books: although it may sound like an easy trick (food for thought and all that), the result was amazing and impressive!

The second piece was a beautiful board illuminated by diodes which felts very warm and comforting, maybe in reminiscence of the maternal womb, of candles, or of myriads of galaxies, but very powerful in any case. (I usually dislike constructs involving light, like the neon sculptures of the 80′s, so I started with an a priori against it.) I could have stayed there for hours…
