free fall [fake]

As I was looking for the location of a picture serving as a background image for Windows 10 log-in page, I came across several versions of the above, supposedly showing a climber failing to grab another climber’s hand and as a result falling. Or “falling” as the image is obviously doctored, most likely by removing […]

New blog hosting!

Hi all. We’ve been having some problems with the blog caching, so that people were seeing day-old versions of the posts and comments. We moved to a new host and a new address, https://statmodeling.stat.columbia.edu, and all should be better. Still a couple glitches, though. Right now it doesn’t seem to be possible to comment. We […]

R Tip: Use seqi() For Indexes

R Tip: use seqi() for indexing. R‘s “1:0 trap” is a mal-feature that confuses newcomers and is a reliable source of bugs. This note will show how to use seqi() to write more reliable code and document intent. The issue is, contrary to expectations (formed in working with other programming languages) the sequence 1:0 is … Continue reading R Tip: Use seqi() For Indexes

Becker on Bohm on the important role of stories in science

Tyler Matta writes: During your talk last week, you spoke about the role of stories in scientific theory. On page 104 of What Is Real: The Unfinished Quest for the Meaning of Quantum Physics, Adam Becker talks about stories and scientific theory in relation to alternative conceptions of quantum theory, particularly between Bohm’s pilot-wave interpretation […]

AIQ [book review]

AIQ was my Christmas day read, which I mostly read while the rest of the household was still sleeping. The book, written by two Bayesians, Nick Polson and James Scott, was published before the ISBA meeting last year, but I only bought it on my last trip to Warwick [as a Xmas present]. This is […]

Babe Didrikson Zaharias (2) vs. Adam Schiff; Sid Caesar advances

And our noontime competition continues . . . We had some good arguments on both sides yesterday. Jonathan writes: In my experience, comedians are great when they’re on-stage and morose and unappealing off-stage. Sullivan, on the other hand, was morose and unappealing on-stage, and witty and charming off-stage, or so I’ve heard. This comes down, […]

MRP (multilevel regression and poststratification; Mister P): Clearing up misunderstandings about

Someone pointed me to this thread where I noticed some issues I’d like to clear up: David Shor: “MRP itself is like, a 2009-era methodology.” Nope. The first paper on MRP was from 1997. And, even then, the component pieces were not new: we were just basically combining two existing ideas from survey sampling: regression […]

Excerpt from Excursion 4 Tour II: 4.4 “Do P-Values Exaggerate the Evidence?”

Excerpt from Excursion 4 Tour II*   4.4 Do P-Values Exaggerate the Evidence? “Significance levels overstate the evidence against the null hypothesis,” is a line you may often hear. Your first question is: What do you mean by overstating the evidence against a hypothesis? Several (honest) answers are possible. Here is one possibility: What I […]

y a plus de mouchoirs au bureau des pleurs

Once the French government started giving up to some requests of the unstructured “gilets jaunes” protesters, it was like a flood or flush gate had opened and every category was soon asking for a rise (in benefits) and a decrease (in taxes) or the abolition of a recent measure (like the new procedure for entering […]

Ed Sullivan (3) vs. Sid Caesar; DJ Jazzy Jeff advances

Yesterday’s battle (Philip Roth vs. DJ Jazzy Jeff) was pretty low-key. It seems that this blog isn’t packed with fans of ethnic literature or hip-hop. Nobody in comments even picked up on my use of the line, “Does anyone know these people? Do they exist or are they spooks?” Isaac gave a good argument in […]

Projecting Unicode to ASCII

Sometimes you need to downgrade Unicode text to more restricted ASCII text. For example, while working on my previous post, I was surprised that there didn’t appear to be an asteroid named after Poincaré. There is one, but it was listed as Poincare in my list of asteroid names. Python module I used the Python module unidecode […]
