the DeepMind debacle

“I hope for a world where data is at the heart of understanding and decision making. To achieve this we need better public dialogue.” Hetan Shah

As I was reading one of the Nature issues I brought on vacations, while the rain was falling on an aborted hiking day on the fringes of Monte Rosa, I came across a 20 July tribune by Hetan Shah, executive director of the RSS. A rare occurrence of a statistician’s perspective in Nature. The event prompting this column is the ruling against the Royal Free London hospital group providing patient data to DeepMind for predicting kidney. Without the patients’ agreement. And with enough information to identify the patients. The issues raised by Hetan Shah are that data transfers should become open, and that they should be commensurate in volume and details to the intended goals. And that public approval should be seeked. While I know nothing about this specific case, I find the article overly critical of DeepMind, which interest in health related problems is certainly not pure and disinterested but nonetheless can contribute advances in (personalised) care and prevention through its expertise in machine learning. (Disclaimer: I have neither connection nor conflict with the company!) And I do not see exactly how public approval or dialogue can help in making progress in handling data, unless I am mistaken in my understanding of “the public”. The article mentions the launch of a UK project on data ethics, involving several [public] institutions like the RSS: this is certainly commandable and may improve personal data is handled by companies, but I would not call this conglomerate representative of the public, which most likely does not really trust these institutions either…

David Spiegelhalter in The Guardian

Posted in Statistics with tags , , , on June 30, 2017 by xi'an

In conjunction with David‘s Presidential Address at the Royal Statistical Society on Wednesday night, the Guardian published a piece covering the talk and its message. Which I find great given that it is not that common to see statisticians on the front-page. (David actually contributes to the Guardian from time to time, as does Neil Lawrence.)

Series B’log

Posted in Books, Statistics, University life with tags , , , , on May 31, 2017 by xi'an

Since the above announcement in the RSS newsletter a few months ago, about the Series B’log coming to life, I have received exactly zero comments from readers, despite several authors kindly contributing an extended abstract of their paper. And announcements to various societies…

Hence I now seriously wonder at the survival probability of the blog, given this collective lack of interest. It may be that the information did not reach enough people (despite my mentioning its existence on each talk I give abroad). It may be that the blog still sounds like “under construction”, in which case I’d like to hear suggestions to make it look more definitive! But overall I remain fairly pessimistic [even conditional on my Gallic gloom] about our chances of success with this experiment which could have turned every Series B paper into a potential discussion paper!

beyond objectivity, subjectivity, and other ‘bjectivities

Here is my discussion of Gelman and Hennig at the Royal Statistical Society, which I am about to deliver!

objective and subjective RSS Read Paper next week

Posted in Books, pictures, Statistics, Travel, University life, Wines with tags , , , , , , , , , , , , , , on April 5, 2017 by xi'an

Andrew Gelman and Christian Hennig will give a Read Paper presentation next Wednesday, April 12, 5pm, at the Royal Statistical Society, London, on their paper “Beyond subjective and objective in statistics“. Which I hope to attend and else to write a discussion. Since the discussion (to published in Series A) is open to everyone, I strongly encourage ‘Og’s readers to take a look at the paper and the “radical” views therein to hopefully contribute to this discussion. Either as a written discussion or as comments on this very post.

latest issue of Significance

Posted in Statistics with tags , , , , on March 20, 2017 by xi'an

The latest issue of Significance is bursting with exciting articles and it is a shame I do not receive it any longer (not that I stopped subscribing to the RSS or the ASA, but it simply does not get delivered to my address!). For instance, a tribune by Tom Nicolls (from whom I borrowed this issue for the weekend!) on his recent assessment of false positive in brain imaging [I covered in a blog entry a few months ago] when checking the cluster inference and the returned p-values. And the British equivalent of Gelman et al. book cover on the seasonality of births in England and Wales, albeit witout a processing of the raw data and without mention being made of the Gelmanesque analysis: the only major gap in the frequency is around Christmas and New Year, while there is a big jump around September (also there in the New York data).

birdfeedA neat graph on the visits to four feeders by five species of birds. A strange figure in Perils of Perception that [which?!] French people believe 31% of the population is Muslim and that they are lacking behind many other countries in terms of statistical literacy. And a rather shallow call to Popper to running decision-making in business statistics.

a somewhat hasty announcement

Posted in Books, Statistics, University life with tags , , , , , on March 13, 2017 by xi'an

When I received the above RSS newsletter on Thursday, I was a bit shocked as I had not planned to make the existence of the Series B’log known to the entire Society. Even though it was already visible and with unrestricted access. The reason being that experimenting with authors and editors was easier without additional email and password exchanges…

Anyway, now that we have jumped that Rubicon, I would more than welcome comments and suggestions to make the blog structure more efficient and readable. I am still confused as to how the front page should look like, because I want to keep the hierarchy of the Journal, i.e., volume/issue/paper, reflected in this structure, rather than piling up comments and authors’ summaries in an haphazard manner. I have started to tag entries by the volume/issue tag, in order to keep some of this hierarchy respected but I would like to also provide all entries related to a given paper without getting into much extra-work. Given that I already have to process most entries through latex2wp in the best scenario.
