A case study in Non-replicability of a Medical paper [YouTube]

A case study in non-replicability of a medical paper. I discuss it with Dr. Fouad Fayad from U.S.J. in Lebanon. Details are in Retraction Watch.

Apparently, the only reply to his case by the study’s lead author is of the fact-free data-free sort “he doesn’t like me” which does not appear to have a statistical explanation.

Note: Retraction Watch did a great job presenting facts, and the attempt to retaliate against Dr. Fayad. Note that the 4 expert reports were not attached. Also, note that the paper violated FDA rules (and those of the corresponding European agency).

Santa Marina

In my ancestral village in the Northern Levant, on top of a hill, stands a church dedicated to Santa Marina. Marina is a local saint, though, characteristically, some other traditions claim her –such as Bithynia or other Anatolian provinces of the Eastern Roman Empire.

[Medium] Foreword for Cut the Knot: Probability Riddles by Alexander Bogomolny

How do you learn a language? There are two routes; the first is to memorize imperfect verbs, grammatical rules, future vs. past tenses, recite boring context-free sentences, and pass an exam. The second approach consists in going to a bar, struggling a little bit and, out of the need to blend-in and integrate with a fun group of people, then suddenly find yourself able to communicate. In other words, by playing, by being alive as a human being. I personally have never seen anyone learn to speak a language properly by the first route. Also, I have never seen anyone fail to do so by the second one.

Informational Rescaling of PCA Maps with Application to Genetics

Nassim Nicholas Taleb∗, Pierre Zalloua, and Dan Platt
∗Corresponding author, nnt1@nyu.edu Dec 2019

We discuss the inadequacy of covariances/correlations and other measures in L-2 as relative distance metrics. We propose a computationally simple heuristic to transform a map based on standard principal component analysis (PCA) (when the variables are asymptotically Gaussian) into an entropy-based map where distances are based on mutual information.
