Children of Earth and Sky [book review]

Posted in Books, Kids, Travel with tags , , , , , , , , on May 27, 2017 by xi'an

While in Dublin last weekend, I found myself without a book to read and walking by and in a nice bookstore on Grafton Street, I discovered that Guy Gavriel Kay had published a book recently! Now, this was a terrific surprise as his Song for Arbonne was and remains one of my favourite books.

There are similarities in those two books in that they are both inspired by Mediterranean cultures and history, A Song for Arbonne being based upon the Late Medieval courts of Love in Occitany, while Children of Earth and Sky borrows to the century long feud between Venezia and the Ottoman empire, with Croatia stuck in-between. As acknowledged by the author, this novel stemmed from a visit to Croatia and the suggestion to tell the story of local bandits turned into heroes for fighting the Ottomans. Although I found unravelling the numerous borrowings from history and geography a wee bit tiresome, this is a quite enjoyable pseudo-historical novel. Except the plot is too predictable in having all its main characters crossing one another path with clockwise regularity. And all main women character eventually escaping the fate set upon them by highly patriarchal societies.  A Song for Arbonne had more of a tension and urgency, or maybe made me care more for its central characters.

Statistical rethinking [book review]

Statistical Rethinking: A Bayesian Course with Examples in R and Stan is a new book by Richard McElreath that CRC Press sent me for review in CHANCE. While the book was already discussed on Andrew’s blog three months ago, and [rightly so!] enthusiastically recommended by Rasmus Bååth on Amazon, here are the reasons why I am quite impressed by Statistical Rethinking!

“Make no mistake: you will wreck Prague eventually.” (p.10)

While the book has a lot in common with Bayesian Data Analysis, from being in the same CRC series to adopting a pragmatic and weakly informative approach to Bayesian analysis, to supporting the use of STAN, it also nicely develops its own ecosystem and idiosyncrasies, with a noticeable Jaynesian bent. To start with, I like the highly personal style with clear attempts to make the concepts memorable for students by resorting to external concepts. The best example is the call to the myth of the golem in the first chapter, which McElreath uses as an warning for the use of statistical models (which almost are anagrams to golems!). Golems and models [and robots, another concept invented in Prague!] are man-made devices that strive to accomplish the goal set to them without heeding the consequences of their actions. This first chapter of Statistical Rethinking is setting the ground for the rest of the book and gets quite philosophical (albeit in a readable way!) as a result. In particular, there is a most coherent call against hypothesis testing, which by itself justifies the title of the book. Continue reading
