class action, really?!

The letter from the US I found in my (home) mailbox last week sounded like a spam building on copyright violations, if an elaborate one, with promises of huge settlement benefits ($3000 per work, for a total of $1.5 billion!) and a California judge authorization stamped on the envelope… However, after being contacted by a co-author and checking on Internet about the existence of a class action against Anthropic and its pirated libraries, I realised this was not (a spam) and checked that the database of the works concerned by this settlement included eight of my books. (Incl. second editions.) Although I do not expect much return (if any!) once the costs and fees and publishers’ share are subtracted, and the remainder split between 7M books!, this is a first instance of getting back at the providers of pirated copies that are everywhere (since publishers came up with the brilliant scheme of provided access to pdf versions!)

“The lawsuit alleges that Anthropic infringed copyrights by downloading datasets containing copyrighted books in violation of the federal Copyright Act. Anthropic denies all the allegations and denies that it did anything wrong. Anthropic argues that its use of the downloaded datasets was fair use. You can get more information about the lawsuit and view related court documents (…) . Copying a work without permission is not copyright infringement if a defendant can show the copying was fair use. If the use is determined to be infringement, the Copyright Act provides for statutory damages of between $200 and $150,000 per work, depending on factors including the harm that was actually caused by the infringement, and whether the alleged infringer reasonably believed its use was fair or instead acted wilfully. If the use was fair (or there was no copying), the defendant owes $0 (…) The resulting Settlement is the largest copyright class action settlement in history. It provides approximately $3,000 per work (not per Class Member), plus interest earned on the Settlement fund, less the Court-approved costs and fees taken out“

sans sérif & sans chevron

{\sf df=function(x)2*pi*x-4*(x>1)*acos(1/(x+(1-x)*(x<1)))}

As I was LaTeXing a remote exam for next week, including some R code questions, I came across the apparent impossibility to use < and > symbols in the sans-sérif “\sf” font… Which is a surprise, given the ubiquity of the symbols in R and my LaTeXing books over the years. Must have always used “\tt” and “\verb” then! On the side, I tried to work with the automultiplechoice LaTeX package [which should be renamed velomultiplechoice!] of Alexis Bienvenüe, which proved a bit of a challenge as the downloadable version contained a flawed file of automultiplechoice.sty! Still managed to produce a 400 question exam with random permutations of questions and potential answers. But not looking forward the 4 or 5 hours of delivering the test on Zoom…

Bayesian Inference, at £1400 per chapter…

Another unsolicited email (“This is a friendly reminder that….”) from a UK operator called IntechOpen about publishing a chapter in an Open Access book about Bayesian Inference. And edited by Tang Niansheng. As detailed on the publisher page

“The aim of this book is to introduce the newly developed Bayesian methods, including Bayesian variable selection (e.g., fixed-dimensional data analysis and high/ultrahigh dimensional data analysis), Bayesian influence analysis (e.g., case deletion method and local influence analysis), Bayesian estimation and clustering methods (e.g., fixed dimensional data, high/ultrahigh dimensional data analysis, Bayesian network, and Bayesian clustering for big data), Bayesian hypothesis test including discrete and continuous random variables, variational Bayesian analysis and Bayesian clinical trials including design and dose-finding algorithm”

which is neither off the mark nor particularly innovative, as Bayesian (hand?)books go. With the slight impediment of a £1400 fee per chapter. Even at the current exchange rate, this is far from “free of charge” (which only applies to the book being “free to download, read and share”. (Given the on-going upheavals of UK politics, it may soon become affordable, though!)

estimation exam [best of]

Yesterday, I received a few copies of our CRC Press Handbook of Mixture Analysis, while grading my mathematical statistics exam 160 copies. Among the few goodies, I noticed the always popular magical equality

E[1/T]=1/E[T]

that must have been used in so many homeworks and exam handouts by now that it should become a folk theorem. More innovative is the argument that E[1/min{X¹,X²,…}] does not exist for iid U(0,θ) because it is the minimum and thus is the only one among the order statistics with the ability to touch zero. Another universal shortcut was the completeness conclusion that when the integral

\int_0^\theta \varphi(x) x^k \text{d}x

was zero for all θ’s then φ had to be equal to zero with no further argument (only one student thought to take the derivative). Plus a growing inability in the cohort to differentiate even simple functions… (At least, most students got the bootstrap right, as exemplified by their R code.) And three stars to the student who thought of completely gluing his anonymisation tag, on every one of his five sheets!, making identification indeed impossible, except by elimination of the 159 other names.

local package delays

When Jean-Michel and I left Berlin, a month ago, I really thought we were that close to sending the new edition of Bayesian Core. Alas, we are not done yet for a series of reasons: leaving for India did not give me enough time to complete the help manual, some codes from the original version did not seem to work any longer, apparently jeopardising a whole chapter!, and the package did not seem to compile. Yesterday, we met again and made progress that makes me much more confident. For one thing, the R code that “did not work” was an original spreadsheet of Bayesian Core that we turned into functions towards the completion of the bayess package. However, due to sloppy programming at the time, we had used global variables that were called inside functions without being (explicitly) declared as variables. When those R codes got turned into functions, variables defined inside those functions were no longer global and recognised by the other functions defined within those same functions… Silly me! Once this issue got spotted by Jean-Michel, as well as the use of a few && instead of &’s, the whole problem unravelled rather quickly and we got a compiled package by the end of the day, even though some of the demos (reproducing the outcome found in the text) are still bugged. Stay tuned!
