perspectives on Deborah Mayo’s Statistics Wars

A few months ago, Andrew Gelman collated and commented the reviews of Deborah Mayo’s book by himself, Brian Haig, Christian Hennig, Art B. Owen, Robert Cousins, Stan Young, Corey Yanofsky, E.J. Wagenmakers, Ron Kenett, Daniel Lakeland, and myself. The collection did not make it through the review process of the Harvard Data Science Review! it […]

Hacking pass codes with De Bruijn sequences

Suppose you have a keypad that will unlock a door as soon as it sees a specified sequence of four digits. There’s no “enter” key to mark the end of a four-digit sequence, so the four digits could come at any time, though they have to be sequential. So, for example, if the pass code […]

Drawing with Unicode block characters

My previous post contained the image below. The point of the post was that the numbers that came up in yet another post made the fractal image above when you wrote them in binary. Here’s the trick I used to make that image. To make the pattern of 0’s and 1’s easier to see, I […]

He’s looking for a Bayesian book

Michael Lewis wrote: I’m teaching a course on Bayesian statistics this fall. I’d love to use your book but think it might be too difficult for the, mainly, graduate social work, sociology, and psychology students likely to enroll. What do you think? In response, I pointed to these two books that are more accessible than […]

Binary surprise

As mentioned in the previous post, the Gauss-Wantzel theorem says you can construct a regular n-gon with a straight edge and compass if and only if n has the form 2k F where k is a non-negative integer and F is a product of distinct Fermat primes. Let’s look at the binary representation of these […]
