Estimating discontinuity in slope of a response function

Peter Ganong sends me a new paper (coauthored with Simon Jager) on the “regression kink design.” Ganong writes: The method is a close cousin of regression discontinuity and has gotten a lot of traction recently among economists, with over 20 papers in the past few years, though less among statisticians. We propose a simple placebo […]

What does CNN have in common with Carmen Reinhart, Kenneth Rogoff, and Richard Tol: They all made foolish, embarrassing errors that would never have happened had they been using R Markdown

Rachel Cunliffe shares this delight: Had the CNN team used an integrated statistical analysis and display system such as R Markdown, nobody would’ve needed to type in the numbers by hand, and the above embarrassment never would’ve occurred. And CNN should be embarrassed about this: it’s much worse than a simple typo, as it indicates […]

Palko’s on a roll

I just wanted to interrupt our scheduled stream of posts to link to a bunch of recent material from Mark Palko: At least we can all agree that ad hominem and overly general attacks are bad: A savvy critique of the way in which opposition of any sort can be dismissed as “ad hominem” attacks. […]

What do you do to visualize uncertainty?

Howard Wainer writes: What do you do to visualize uncertainty? Do you only use static methods (e.g. error bounds)? Or do you also make use of dynamic means (e.g. have the display vary over time proportional to the error, so you don’t know exactly where the top of the bar is, since it moves while […]

They know my email but they don’t know me

This came (unsolicited) in the inbox today (actually, two months ago; we’re on a delay, as you’re probably aware), subject line “From PWC – animations of CEO opinions for 2014″: Good afternoon, I wanted to see if the data my colleague David sent to you was of any interest. I have attached here additional animated […]

More bad news for the buggy-whip manufacturers

In a news article regarding difficulties in using panel surveys to measure the unemployment rate, David Leonhardt writes: The main factor is technology. It’s a major cause of today’s response-rate problems – but it’s also the solution. For decades, survey research has revolved around the telephone, and it’s worked very well. But Americans’ relationship with […]

Mon: More bad news for the buggy-whip manufacturers Tues: They know my email but they don’t know me Wed: What do you do to visualize uncertainty? Thurs: Sokal: “science is not merely a bag of clever tricks . . . Rather, the natural sciences are nothing more or less than one particular application — albeit […]

Six quotes from Kaiser Fung

You may think you have all of the data. You don’t. One of the biggest myth of Big Data is that data alone produce complete answers. Their “data” have done no arguing; it is the humans who are making this claim. Before getting into the methodological issues, one needs to ask the most basic question. […]

He just ordered a translation from Diederik Stapel

Fernando Martel Garcia writes: So I am applying for a DC driver’s license and needed a translation of my Spanish license to show to the DMV. I go to http://www.onehourtranslation.com/ and as I prepare to pay I see a familiar face in the bottom banner: It appears Stapel is one of their “over 15,000 dedicated […]

What is the purpose of a poem?

OK, let’s take a break from blogging about economics. OK, I haven’t actually been blogging so much about econ lately, but it just happens that I’m writing this on 19 July, a day after poking a stick into the hornet’s nest by posting “Differences between econometrics and statistics: From varying treatment effects to utilities, economists […]
