I blogged about data model and likelihood being different things and importance of using these terms correctly (with some excerpts from the forthcoming Bayesian Workflow book, but we talk about these much more in the book)

New short paper forthcoming in Statistics & Probability Letters: An objective non-local prior for skew-symmetric models. arxiv.org/abs/2603.08285 This paper develops a Moment-Objective Minimum-Discrepancy (MOOMIN) Prior for testing symmetry against skew-symmetric alternatives.

Super excited to see that somebody finally wrote about this 🥳 If you do research about research, you really need causal thinking (just like when you do research about anything else really).

Episode 2 of my trilogy on building replication packages for social scientists is now out! i4replication.org/a-researcher... 😉

Interesting take! Feels intuitively correct, but I think it's something that probably could be tested empirically.

So...my undergrad thesis student is doing a quality analysis of studies found in meta-analyses. She identified a few and we contacted the authors to request their effect sizes and other variables for the studies in their papers. Here's what happened: scientiapsychiatrica.com/index.php/Sc...

Have you seen this gem of a resource for #DataViz with R?!

The AI Summit is today! We look forward to celebrating the opening of ELLIS Institute Finland and hearing from stellar speakers in AI research, business and government. Tune in to the livestream areena.yle.fi/1-76514739 starting at 10:00 EET. Check out the program here: aisummit.fi @ellis.eu

The link between the gut #microbiome and autism is not backed by science, researchers say. Read the full opinion piece in @cp-neuron.bsky.social: spkl.io/63322AbxpA#microbiome @wiringthebrain.bsky.social, @statsepi.bsky.social, & @deevybee.bsky.social

I had a lovely catch up chat with @jamesheathers.bsky.social at the weekend. I am thoroughly inspired by the work he and team are doing at the Medical Evidence Project. They act on tip offs for fraudulent and/or inaccurate science used to shape medical practice. Know any? medicalevidenceproject.org

Very cool (from Ehm-Gneiting-Jordan-Krüger, JRSSB 2016): for mean estimation, all consistent scoring rules can be obtained as conic combinations of 'extremal' consistent scoring rules, with an explicit structure. Similar results hold for quantiles (and perhaps other tasks as well!).

I appreciate @bmj.com follows a formal process, but just how much evidence do they need before adding an Expression of Concern. Numerous PubPeer comments for stem cell for heart disease paper - which had huge media attention hailing it as a medical breakthrough. pubpeer.com/publications...

I am excited to share that I am looking for a #postdoc with an interest in causal machine learning to join my lab at TU Dortmund University and RC Trust. #hiring #causality #ML #AI 📅 03.12.25 Group: rc-trust.ai/groups/causa... Details: tinyurl.com/4622p6at

Multiverse analysis! 👁️👁️

You can now find a recording of my course "Introduction to Bayesian Statistics in R & brms" on youtube. Slides & code available here: github.com/benjamin-ros... #Rstats

The detectCores() apocalypse is creeping up on us 👻🐛 As more people are getting access to 128+ CPU cores, code spinning up parallel cluster with detectCores() workers fails - not enough #RStats connections available Friends, do *not* default to detectCores(), bc www.jottr.org/2022/12/05/a...

Now I'm also looking for a research software engineer to implement a pile of research results to R packages loo, posterior, bayesplot, projpred, priorsense, brms or/and Python packages ArviZ, Bambi and Kulprit. Apply by email with no specific deadline (see contact info at users.aalto.fi/~ave/)

We wrote an article explaining why you shouldn't put several variables into a regression model and report which are statistically significant - even as exploratory research. bmjmedicine.bmj.com/content/4/1/.... How did we do?

How FAIR is shared data in psychology? We analyzed 11,384 datasets (2013–2024): They're findable, but less reusable! What relates most to differences in FAIRness? #Repository choice. 👉 Preprint: doi.org/10.23668/psy... @mariogollwitzer.bsky.social @kaisassenberg.bsky.social #metascience #SciSci

Write code to make being human easier. Rip code out if it makes being human harder. Write code to make caring for each other easier. Rip it out if it makes caring for each other harder. Empathy driven development has literally never failed me. It’s done me better than everything else combined

Took part yesterday in @freieuniversitaet.bsky.social's Replication Games, it was such a nice experience! People were lovely and the work was a very fun challenge. Thanks to @i4replication.bsky.social and @janmarcus.de for organizing this, it was absolutely worth enduring the ride from Dortmund. 😄

🚨I4R is looking to hire postdoc fellows in public health and computer science! The postdoc will join a team of researchers and help mass reproduce studies in leading public health journals or develop AI replicator agents. Info 👇
