We should make a much bigger deal about the fact that Prof Ostermann is the first female ESICM president. Congratulations!

It’s only causal inference if it comes from the Inférènce region of France, otherwise it’s just a sparkling correlation.

(1/22) Over the last few days I have been discussing the role of formal causal inference in RCTs, and in general the role of formalism and rigor in statistics in twitter with @f2harrell.bsky.social. Thread with an example for why both are fundamental for biomedical research:

Big news! 🎉 𝚖𝚊𝚛𝚐𝚒𝚗𝚊𝚕𝚎𝚏𝚏𝚎𝚌𝚝𝚜 1.0.0 for #Rstats is out. It’s a big number and it feels like a big step. I wrote a blog on the challenges of interpreting statistical models, SPEED, cool new features, the future, and a 5 year package development and writing odyssey. arelbundock.com/posts/margin...

In this special episode of Learning Bayesian Statistics, @alex-andorra.bsky.social is joined by Andrew Gelman, Aki Vehtari, and Richard McElreath to discuss Bayesian Workflow. From simulation and hierarchical pooling to causal inference, there’s a lot to unpack 🎧 lnkd.in/geX2QkxV #Bayesian

Editors should not accept for publication papers using the phrase «real world evidence». It’s a marketing term, to embellish non-causal studies. #metasci #stats #cardiosky www.ahajournals.org/doi/10.1161/...

All four books I've co-authored are freely available online for non-commercial use: - Bayesian Workflow at avehtari.github.io/Bayesian-Wor... Links to other three books are in the quoted post 👇 (too many books to fit in one post!)

The Statistical Society of Australia has a new President... No, it's not Randy the greyhound (although he would've done a fine job) It's me! If you want to know a little more about me, I have the blog post just for you :) benharrap.com/post/2026-08... #statssky #datascience

I, for one, welcome my new overlord

we have got to put that into a causal inference lecture

New blog post in which we discover the secret to immortality: accounting errors. www.the100.ci/2026/08/08/m...

Me, once a month #statsky #rstats

New blog post! Odds ratios are...a bit weird. Here I explain two problems (interpretation, non-collapsibility) and provide some simple recommendations for improved reporting. www.the100.ci/2026/07/30/r...

Thank you for your kind words 2 responses: 1/ Source control is good for patients with sepsis, so if we can find the right patients, this could be more than just marginal for those patients 2/ ICU care in general is a game of inches; much of excellence is just cumulating marginal benefits, right?

You know you’re getting old when the consultants look like interns!

Ha! These young ones with their gaming! They can’t even spell estimate properly!

Our latest blog is out: The Nothing-to-Lose Fallacy https://criticalcarereviews.com/2026/the-nothing-to-lose-fallacy

Holy shit!!!!! I was today years when I learned…

I fear this is a losing battle, but I'm trying very hard to avoid using the term "AI". a word that can refer to anything from LLMs/GenAI through to control systems and prediction models through to linear regression has no useful meaning at all

happy pi approximation day (22/7) to all those who celebrate

Modelling makes a difference, but the problem here starts with including an SMD of >2. That sounds like an error, and probably is an error or fraud. Trustworthiness assessment www.medrxiv.org/content/10.1... would be in order @ianhussey.mmmdata.io

We are all statisticians 😜 statsepi.substack.com/p/im-not-a-r...

I have just resigned from the board of "Statistics and Computing", along with 17 other Associate Editors. This was a difficult decision: this great journal has published many tremendous articles under the leadership of EiC Ajay Jasra, and before him David Hand, Gilles Celeux, and Mark Girolami.

This one I find really interesting ever since one of the American ED physicians introduced me to the idea of the “physiologically difficult”airway. An AFOI negates precipitous falls in BP and CVS collapse. If. You know what you’re doing 🤔 #ansky

it all comes back to the age-old question: WHat's Your Fucking Estimand, Motherfucker

I am giving away a free copy of the #BayesianWorkflow book by @statmodeling.bsky.social, @avehtari.bsky.social, @rmcelreath.bsky.social et al!! Please like, repost, and follow to enter. I will randomly draw the winner next Weds July 8. 😀 routledge.com/9780367490140 #RStats #DataScience #Bayesian

This paper is worth it for table 1 alone. 👏 @sabinehoffmann11.bsky.social @boulesteixlaure.bsky.social et al onlinelibrary.wiley.com/doi/10.1002/...

This is really cool!!!

Going to start explaining heated rivalry to Australians by saying imagine if Shane Warne and Mike Gatting had also somehow been in a secret relationship when the ball of the century happened

The standard random-effects model in meta-analysis assumes that the amount of heterogeneity is homoscedastic. This assumption may not be true. I derived and examined various tests for heteroscedastic heterogeneity. See osf.io/cavhy for a preprint describing these methods. #MetaAnalysis #RStats

No disrespect, Australia, but "Our land abounds in nature's gifts"???

There's nothing like a bit of good news to brighten up the week! Not only did my abstract on data missingness and questionnaire redesign get accepted for the Australasian Epidemiological Conference 2026 (in Fiji!), but I'm delivering an Intro to #rstats workshop there too!! 🎉🎉🇫🇯🌴🥥

Today we celebrate the awarding of the prestigious Rousseeuw prize to the R Core team in recognition of their 30 years of dedicated work on R and in recognition of the massive impact of R on the scientific community rousseeuwprize.org/2026 #RStats

Check out the great program of the *1st Interdisciplinary Symposium on Meta Science for Methods Research* organized 31 August and 1 September in Zürich! Ton of cool speakers and meta-methodological reseach! crsuzh.pages.uzh.ch/msmr/program/ (registration still open)

Having a visual component when you are teaching a new concept is always something I value. I went back and redid some old diagrams as animations This website has all mp4, gif and code for you to use yourself in slides of websites! emilhvitfeldt.github.io/tidy-animati... #rstats #quarto #dataBS

The SNaPP Study results were published today in Lancet Respiratory Medicine. The publication can be viewed here: www.thelancet.com/journals/lan... A podcast with Kate Leslie can be found here from Fri June 12th: www.topmedtalk.com Congrats to all involved! @anzca.bsky.social @katy-skier.bsky.social

Imagine you’re evaluating a new cancer treatment. It reduces tumor size in most patients, but some experience severe side effects. Would we consider the new treatment better? Read more about it in a new post on superiority in the multivariate context. bit.ly/4e97n4n #statistics #bayesian #rstats

You mean I should do an Australian version of this? 😂 bsky.app/profile/pwgt...

You'll just need to add a subtitle for the Australian tour poster Have DAGs fulfilled their promise? Yeah nah yeah

fuck yeah!
