When anova() doesn't do ANOVA: A short post on what R's anova() function actually does when you use it to compare mixed-effects models, why you should take its output with a pinch of salt, and how you can obtain more accurate results. janhove.github.io/posts/2026-0...

A brave and tough call to make. It's hard to overstate how influential OSF has been on science in the past ~15 years. It's been such a staple that you'd almost forget how much cost, time, and effort it must be to keep going. Kudos to the OSF team for everything they've done.

Over the next several months, we will phase out some popular OSF features. These changes do not affect current public content, which remains safe and accessible. We have prepared support material to help users adapt. I am very sorry for the disruption to your work. Please read this post for details.

Ah well. Time to rewrite my lecture notes on data and code sharing.

"A random variable P is called an exact p-value if Prob(P ≤ α | Hₒ) ≤ α for each α ∈ (0,1)." Most general definition. Doesn't explain how you can construct such P, why some constructions are more useful than others, what approximate p-values are, or why anyone might care, in fairness.

You suddenly get a narrator describing your life and there’s no way to turn it off - everyone can hear it. While shopping, at work, at home, with friends - the voice narrating your every move goes on. Who do you hope is the voice of this narrator?

A new blog post in which I discuss the strong and weak null hypotheses in randomised experiment and how they can be tested: janhove.github.io/posts/2026-0... These tests don't rely on sampling assumptions but on more easily verifiable assignment assumptions.

I quite often give students a few arbitrarily selected excerpts in which the article they've read is cited and ask them to compare what was done in the article vs what they would've thought was done in the article based only on the reference. Makes for interesting discussions.

Sometimes co-authors ask me “did you see what they cited us for???” and of course I didn’t, because if you want to keep faith in humanity, you don’t look up what people cite you for, just like you don’t read comment sections.
