How post-hoc power calculation is like a shit sandwich

Damn. This story makes me so frustrated I can’t even laugh. I can only cry. Here’s the background. A few months ago, Aleksi Reito (who sent me the adorable picture above) pointed me to a short article by Yanik Bababekov, Sahael Stapleton, Jessica Mueller, Zhi Fong, and David Chang in Annals of Surgery, “A Proposal […]

Johnny Carson (2) vs. Paul Erdos; Babe Didrikson Zaharias advances

OK, our last matchup wasn’t close. Adam Schiff (unseeded in the “people whose name ends in f” category) had the misfortune to go against the juggernaut that was Babe Didrikson Zaharias (seeded #2 in the GOATs category). Committee chair or not, the poor guy never had a chance. As Diana Senechal wrote, “From an existential […]

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, […]

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 […]

Philip Roth (4) vs. DJ Jazzy Jeff; Jim Thorpe advances

For yesterday’s battle (Jim Thorpe vs. John Oliver), I’ll have to go with Thorpe. We got a couple arguments in Oliver’s favor—we’d get to hear him say “Whot?”, and he’s English—but for Thorpe we heard a lot more, including his uniqueness as greatest athlete of all time, and that we could save money on the […]

Using multilevel modeling to improve analysis of multiple comparisons

Justin Chumbley writes: I have mused on drafting a simple paper inspired by your paper “Why we (usually) don’t have to worry about multiple comparisons”. The initial idea is simply to revisit frequentist “weak FWER” or “omnibus tests” (which assume the null everywhere), connecting it to a Bayesian perspective. To do this, I focus on […]

A couple of thoughts regarding the hot hand fallacy fallacy

For many years we all believed the hot hand was a fallacy. It turns out we were all wrong. Fine. Such reversals happen. Anyway, now that we know the score, we can reflect on some of the cognitive biases that led us to stick with the “hot hand fallacy” story for so long. Jason Collins […]
