Nice. Related to a WIP with @jdushoff.bsky.social : bbolker.github.io/powertargets... : basically, extending power analyses to see which bin we'll fall in (I do agree that CIs are better!)

Our paper is finally out in Cognition! 🎉
We introduce the "CLIP task"—a computerized paradigm for measuring numerical bias in adults: when number and physical size both matter, do you spontaneously rely more on numbers or on physical size?

A bayesian t-test is like cutting a birthday cake with a chainsaw. It works, but it's extra power. But trying to fit multilevel models without Bayes is like trying to cut down a tree with a pocket knife. You can do it, but it's the wrong way to it. It's worse in every way. #rstats #StatsSky

Explainers & tutorials are a great way to criticize current practices with a positive twist. Tailoring them to a specific substantive (!) subfield can greatly increase uptake. Forget about novelty; if some statistican said sth in the 70s but no one was around to hear it, say it again.>

I know some people that are guaranteed to "fail" check_sessiontime() with sessions open for *months*!
A request for #rstats help.
Motivated by a real-world problem I'm facing, I wrote a package designed to help new users wean themselves off using rm(list=ls()), and nudge them in the direction of better practice.
I would sincerely appreciate feedback before I send it to CRAN

was looking at a paper, got confused about its statistical methods, went down a rabbit hole on Bayesian stats, and now I both have a headache and don't trust frequentist methods
