I am a professor of Statistics at both Université Paris Dauphine, Paris, France, and University of Warwick, Coventry, United Kingdom, with a definitely unhealthy (but so far not fatal) fascination for mountains and (easy) climbing, in particular for Scotland in Winter, an almost daily run, and a reading list mainly centred on fantasy books… Plus an addiction to bloggin’ since 2008! Hence the categories on this blog (or ‘og, because ‘log and b’og did not sound good). The Statistics posts do mainly focus on computational and Bayesian topics, on papers or preprints I find of interest (or worth criticising), and on the (not so) occasional trip abroad to a research centre or to a conference.

Needless to say (?), this blog is not approved by, supported by, or in any other way affiliated with the Université Paris Dauphine, CREST-INSEE, University of Warwick, or any other organization, and it only reflects my opinions. This is also one of the reasons why it is posted on wordpress rather than on my University webpage, another one being that wordpress provides a handy (if sometimes slow) tool for editing blogs…

  2. Hi Xi’an,

    I found your blog while browsing GoodReads.com and have enjoyed reading through your thoughtful, thorough, and honest book reviews. The description of your blog noted that you review non-fiction science books, which is thrilling to discover (and admittedly difficult to find!). I am a pharmacist by trade, author, science enthusiast, and mom to a very energetic and inquisitive analytical thinker. Given my background coupled with the drive to teach my own little one, I have created the “Think-A-Lot-Tots” collection of educational science books for babies, toddlers, and kids (pre-K & elementary school).

    The goal in developing these books is to introduce scientific concepts to young readers as well as build upon their vocabulary. I am both writer and illustrator, so creating these has been especially rewarding. I currently have 3 books available on Amazon; 2 of which are books-to-be-read and are geared towards biology; 1 is a book-to-be-written-in that acts as a hands-on notebook outlining the scientific method. If you have time and are interested, would you be willing to review one of the books I have available?

    All 3 titles can be found on my Amazon author page below. I am open to having you review whichever you find most interesting and would be happy to send you the PDF copy of your choice:

    Self-published titles currently available:
    Think-A-Lot-Tots: The Animal Cell
    Think-A-Lot-Tots: The Neuron
    Think-A-Lot-Tots: My Science Lab Notebook

    Many thanks for your time and consideration!



  3. Greetings Xi’an-

    I really enjoyed browsing your blog and reading some of your reviews. I was hoping you might be interested in reviewing my newly released novel. It is the second book in a series, so I can furnish the first book as well if you are interested.

    Author: Lars Teeney

    Title: The Apostates Book Two: Remnants
    Genre: Science Fiction/Dystopian/Post-Apocalyptic
    After the fall of the ruling Regime of New Megiddo, the John W. Schrubb Administration, the remnants of the country are fought over by the Republic of China Army, the Societatum Pentagram, ‘Database’ cartels, and independent city-states. Greta Sanchez, a former Apostate resistance commander who had sought refuge in West Europa is haunted by the nuclear annihilation of the old capital, New Megiddo City. In order to atone for her complicity in the destruction, she resolves to return to America to stop a new war. Greta sets out to track down her old comrades to reform the Apostates to meet new threats.

    It features a diverse racial, gender and orientation cast of characters.

    200 Pages
    I have epub or .mobi I can send.

    Thank you,
    Lars Teeney

  7. I genuinely enjoy reading your blog. Statistics bas always been quite boring and… detached. Then computers fixed it.

    Keep up the good stuff!

  9. Igor Carron pointed out to me that your feed is not displayed correctly on mathblogging.org . This seems to be due to some non-utf8 part of your feed-xml (at least that’s what chrome tells me — I couldn’t find the actual culprit).

    In any case, if you have the time to fix it, that’d be great!

    • Peter, thank you for contacting me, this problem with non utf-8 characters already happened once with R-bloggers. In each case, a cut and paste from pdf documents introduced an fi ligature that I did not spot. I have removed an in#nity entry in the Semi-automatic ABC [revised] post, hope this solves the issue. Thanks!

    I’m trying to use mapvariable (in R’s SpatialEpi package) but I can’t change the default grey colours. I’ve noticed that you managed to do that (A quantum leap (CoRe in CiRM [4]) – posted on July 13), but the link to your ‘modified mapvariable’ is corrupted.
    Could you please send me the code to change the colours in the plots rendered with the mapvariable function?
