Is there a Kindle edition of Practical Data Science with R?

We have often been asked “why is there no Kindle edition of Practical Data Science with R on Amazon.com?” The short answer is: there is an edition you can read on your Kindle: but it is from the publisher Manning (not Amazon.com). The long answer is: when Amazon.com supplies a Kindle edition readers have to … Continue reading Is there…

Derailment: Faking Science: A true story of academic fraud, by Diederik Stapel (translated into English)

Diederik Stapel’s book, “Ontsporing” has been translated into English, with some modifications. From what I’ve read, it’s interesting in a bizarre, fraudster-porn sort of way.

Sokal: “science is not merely a bag of clever tricks . . . Rather, the natural sciences are nothing more or less than one particular application — albeit an unusually successful one — of a more general rationalist worldview”

December 20, 2014
By

Alan Sokal writes: We know perfectly well that our politicians (or at least some of them) lie to us; we take it for granted; we are inured to it. And that may be precisely the problem. Perhaps we have become so inured to political lies — so hard-headedly cynical — that we have lost our […] The post Sokal: “science…

The Use of Sampling Weights in Bayesian Hierarchical Models for Small Area Estimation

December 19, 2014

All this discussion of plagiarism is leaving a bad taste in my mouth (or, I guess I should say, a bad feeling in my fingers, given that I’m expressing all this on the keyboard) so I wanted to close off the workweek with something more interesting.

Defense by escalation

December 19, 2014
By

Basbøll has another post regarding some copying-without-attribution by the somewhat-famous academic entertainer Slavoj Zizek. In his post, Basbøll links to theologian and professor Adam Kotsko (cool: who knew there were still theologians out and about in academia?) who defends Zizek, in part on the grounds that Zizek’s critics were being too harsh. Kotsko writes of […] The post Defense by…

Message to Booleans: It’s an additive world, we just live in it

December 18, 2014
By

Boolean models (“it’s either A or (B and C)”) seem to be the natural way that we think, but additive models (“10 points if you have A, 3 points if you have B, 2 points if you have C”) seem to describe reality better—at least, the aspects of reality that I study in my research.
