My friend Natalia has posted a link to this blog on her Facebook profile. Basically, this is the story of a paper published in 1994 in the medical journal Diabetes Care. As it turns out, this paper "discovered" a method to: 1) determine total...

This post is by David K. Park As we have witnessed, the term “big data” has been thrusted onto the zeitgeist in the past several years, however, when one pushes beyond the hype, there seems to be little substance there. We’ve always had “data” so what so unique about it this time? Yes, we recognize it’s […] The post Big Data…Big Deal? Maybe, if Used with Caution. appeared first on Statistical…

Paul Alper writes: For years I [Alper] have been obsessed by the color of the line which divides oncoming (i.e., opposing) traffic because I was firmly convinced that the color of the center line changed during my lifetime. Yet, I never could find anyone who had the same remembrance (or interest in the topic). The […] The post White stripes and dead armadillos appeared first on Statistical Modeling, Causal Inference,…

S. Stanley Young, PhD Assistant Director for Bioinformatics National Institute of Statistical Sciences Research Triangle Park, NC Here are Dr. Stanley Young’s slides from our April 25 seminar. They contain several tips for unearthing deception by fraudulent p-value reports. Since it’s Saturday night, you might wish to perform an experiment with three 10-sided dice*,recording the results of 100 rolls (3 at a time) […]

Après les exposés des dernières séances, l’examen du cours MAT8595, Copules et Valeurs Extrêmes avait lieu hier matin. L’énoncé est en ligne, et j’ai aussi écrit quelques éléments de correction, là. En cas de désaccord, m...

Some asshole who has a bug up his ass about compressed sensing is spamming our comments with a bunch of sock puppets. All from the same IP address: “George Stoneriver,” Scott Wolfe,” and just plain “Paul,” all saying pretty much the same thing in the same sort of broken English (except for Paul, whose post […] The post Sleazy sock puppet can’t stop spamming our discussion of compressed sensing and…

Here are the slides of the tutorial on ABC methods I gave yesterday at both AISTAST 2014 and MLSS. (I actually gave a tutorial at another MLSS a few years ago, on the pretty island of Berder in Brittany, next to Vannes.) They are definitely similar to previous talks and tutorials I delivered on this […]

Yesterday, I attended an interesting seminar called “Transforming Healthcare through Big Data” at the Providence Health Care Research Institute‘s 2014 Research Day. The seminar was delivered by Martin Kohn from Jointly Health, and I enjoyed it overall. However, I noticed a glaring error about basic statistics that needs correction. Martin wanted to highlight the overconfidence that many doctors have […]

An earlier post, DNS/AFNS Yield Curve Modeling FAQs, ended with:"What next? Job 1 is flexible incorporation of stochastic volatility, moving from \(A_0(N)\) to \(A_x(N)\) for \(x>0\), as bond yields are most definitely conditionally heteroskedastic....

Here's the finalised programme for Bayes Pharma. (Of course I may be biased), but I think it is quite interesting and we have a wide variety of topics, so there should be plenty to get your teeth into! We still have some places available (and as a...

As regular readers of this blog are aware, a few months ago Val Johnson published an article, “Revised standards for statistical evidence,” making a Bayesian argument that researchers and journals should use a p=0.005 publication threshold rather than the usual p=0.05. Christian Robert and I were unconvinced by Val’s reasoning and wrote a response, “Revised […] The post Revised statistical standards for evidence (comments to Val Johnson’s comments on our…
