The 2026 Rousseeuw Prize for Statistics has been awarded to the R Project. #RStats www.rousseeuwprize.org/2026

The 2026 laureates are Brian Ripley, Martin Maechler, Kurt Hornik, Peter Dalgaard, and Luke Tierney who have made the longest sustained contribution to #RStats. Half of the $1m prize money is awarded to the laureates and half to the rest of the Core Team.

Interested in doing a PhD with me in epidemiology on causal inference and triangulation? In beautiful Rotterdam no less. www.werkenbijerasmusmc.nl/en/vacancy/1... Pro tip: if you get to the interview stage, there WILL be a question about ice hockey

This looks like a great package 👇

"a ‚significant' p-value between 0.01 and 0.05 should be interpreted with the expectation that the effect is exaggerated by more than 50% (median 1.56) and that an exact replication has about a one-in-three chance of also being significant." evidenceinthewild.com/p-value-look...

We just published a blog post on AI-generated papers in the Position Paper Track. The core issue is not whether AI can be useful, but who bears the cost of verifying AI-generated text in peer review. We have desk-rejected around 30% of submissions, with roughly 60% of these w/o an appeal option.

The program is up for the first 1st Interdisciplinary Symposium on Meta Science for Methods Research and it promises to be a BANGER! crsuzh.pages.uzh.ch/msmr/program/

This is a great article which helped me a lot in preparing teaching materials for case control studies 👇

It puzzled me for a long time that people acted like estimates from cc studies can simultaneously have two interpretations, eg an RR and a cc OR. So I wrote this: pubmed.ncbi.nlm.nih.gov/32889542/

I would love to see more applied researchers attending and presenting at ACIC. So many interesting problems at the applied-theoretical interface. If you are an applied researcher with interests in causal inference, consider submitting a symposium proposal for the Pittsburgh conference!

New post! Are you following @sketchplanations.bsky.social ? He is great at explaining complex ideas via text and images, and some of those complex ideas are statistical.

Ugh. Here comes the language police saying I can't use the word association! (You definitely can use the word association but to mean what it's actually supposed to me!)

I worked on this exact formalization for about a month last fall before getting lost and distracted (just wanted to understand, not for a paper!) so I'm very happy to have a clean answer. @edwardhkennedy.bsky.social and friends are such gems in our community.

A very nice to initiative where you can post your DAG: opencausal.org And because they're machine readable, they're much easier to search.

When does associational language make sense and when does it not? Katrina Kezios and I cover this in "How and when to use causal and associational language" with 3 suggestions for which concepts require causal language and which can be described in associational language.

Speaking with my R Foundation board member hat on: Indeed. It had been coming for some time, but details schmetails as always including of course payments as money still makes the world go around. But scientific software is a scientific output, and should -- and can !! -- be cited.

As an editor I often see authors fall into a trap of stressing some fancy statistical technique for estimating causal effects. Often neglected are the necessary assumptions to map the data to the estimand. @pausalz.bsky.social and I wrote about it here www.bmj.com/content/391/... #EpiSky

A lot of people seem to be under the impression that causal inference mak you more certain about causation. It sometimes can but often it just shows you all the ways your study could be spectacularly wrong.

This week's episode is on the Manipulation Theorem, which is not well-known in the broader causal community, but has hugely influenced philosophers. I cover hard vs soft interventions, why causation doesn't require human agents, and whether causation requires open systems. youtu.be/fg1ApidilVM

In longitudinal studies, dropout leads to a monotone missing data pattern. We show in a new article that monotonicity sometimes enables and sometimes prevents the identification of  the full law, i.e., the joint distribution of actual variables and response indicators. openreview.net/pdf?id=kVthd...
