🆘 Help! 🆘 How should we treat subjects lost to follow-up in an agricultural trial & does it change if H0 being tested is some form of "assuming the subject makes it to time period x, there is no diff between treatment & control groups"? stats.stackexchange.com/q/676127/1390 #statistics #RStats

Stan embedded Laplace was a long project and happy that it's finally released. We are not competing with INLA and TMB software, as they are orders of magnitude faster and scale better with data size for models that you can implement with them 1/

I made Conway–Maxwell–Binomial regression on #TMB + #glmmTMB. A bounded-count family that handles both over- and under-dispersion through one parameter.. Demo on coral fertilization data from @benoitpujol.bsky.social #rstats #STEM #biology jbogomolovas2.github.io/Julius-s-Blo...

Great paper that underpins this work, as well as models used for the waste water surveillance for SARS-CoV-2 in Ireland. bsky.app/profile/stat...

#StatsPubs No matter how many times you read it, this paper on hierarchical GAMs keeps giving. Clear model explanations together with R code (mgcv). So useful! doi.org/10.7717/peer... Thanks for writing @ericjpedersen.bsky.social, D. Miller, @gsimpson.bsky.social @noamross.net

Thanks ❤️ Writing this paper with Eric, Noam & Dave (order determined by `sample()`) was a pleasure & has resulted in not just a thing that has proven useful to a wide range of folk, but to long lasting friendships with some genuinely nice people who also happen to be very knowledgeable about stuff

Excellent tweetorial by @ericjpedersen.bsky.social on Simon Wood’s new Neighborhood Cross Validation smoothness selection method, which is especially useful when fitting data with temporal and spatial dependence among observations

Prof. Aono tracked a specific species — Yamazakura (Prunus jamasakura) — in a specific place: Arashiyama, Kyoto. We've contacted his university, local organizations, and weather services, but unfortunately none can continue the series. We’re looking for someone who can help us continue it!

You can help if you: 🌸 Have botanical expertise and can identify Yamazakura peak bloom from photos 🌸 Are local to Arashiyama and have access to species-specific bloom reporting Please DM me here or email me at [email protected]. Even a lead helps — thank you!

I'm a data scientist @ourworldindata.org and I need help from a botanist or someone local to Kyoto, Japan! 🌸 We present one of the world’s longest climate records: 1,200 years of peak cherry blossom dates in Kyoto. The researcher who maintained it, Prof. Yasuyuki Aono, sadly passed away last year.

I'm excited to see this out! It's also a nice coincidence, as @gsimpson.bsky.social and I just got phylogenetic smoothers working (for BM and OU processes) in our MRFtools package. I'll definitely be pointing people to your book for background. gam-mafia.github.io/MRFtools/art...

Registration is now open for the Physalia online course GLLVMs: Advanced Multivariate Analysis in R (7–10 July) led by @vdveenb.bsky.social Join us to learn model-based ordination, JSDMs, and multispecies GL(M)Ms. Hands-on in R! www.physalia-courses.org/courses-work... #Ecology #RStats #GLLVM

I know there are a lot of ecologists out there who are JDSM curious, but get scared off by how technical the primary literature is... Here's your chance to learn how they work. Strongly recommend this to anyone who is interested in species distribution modelling. #Rstats

Self-feedback loops matter. The model drafts, critiques itself, retrieves more context if needed, and refines. Everything is open-source: models, code, data store, and a new benchmark (ScholarQABench). 3/3 www.nature.com/articles/s41...

The citation problem is severe: GPT-4o fabricates 78-90% of citations when asked to cite recent papers. OpenScholar achieves citation accuracy on par with human experts by grounding responses in 45M open-access papers. 2/3

I've always been a fan of what the Allen Institute is doing. New in Nature: OpenScholar, an 8B RAG model for scientific literature, outperforms GPT-4o by 6% on correctness. Experts preferred its answers over human-written ones 51%-70 of the time. www.nature.com/articles/s41... 1/3 🧵

inspired by CLAUDE.md, I’ve started putting markdown files named after coworkers into work code repos so I can remind them to stop doing shit to the codebase that annoys me for some reason they’re all mad at me now, which means ill be adding commands to JEREMY.md for an attitude adjustment

While Ukrainians face 30+ hour blackouts, Moscow's Higher School of Economics hosts seminars with top international speakers-then uses the same rooms for drone fundraisers. Academics don't get paid for seminars. So why present at an institution actively funding mass murder of Ukrainians? #Econsky

Ok science hivemind 🧪. I have a distinct memory of an awesome graphic in a paper about how environmental filtering and biotic interactions determine whether an organism can live in any given place. Almost like multiple filter layers on top of another. Does anyone have a preferred graphic of this?

If you mentor scientific writers, teach a course with written assignments, or anything similar, you know how much work is involved, and how difficult it can be to provide the guidance developing writers need. This book is for you! 2/2

Over the holiday, while folks were on well-deserved breaks, our new book was released! Mentoring writers is hard - we can make it easier for you. Please help spread the word - repost this, tell your colleagues, etc. scientistseessquirre... 1/2

I'm teaching Statistical Rethinking again starting Jan 2026. This time with live lectures, divided into Beginner and Experienced sections. Will be a lot more work for me, but I hope much better for students. I will record lectures & all will be found at this link: github.com/rmcelreath/s...

We are recruiting several PhD students. If you are interested in conservation conflicts, population ecology, quantitative ecology, or biodiversity, check these projects out (links in the thread, feel free to reach out):

It's official - my new book is officially published today! If you mentor science students who write - grad or undergrad - you're the reason we wrote this. Mentoring/teaching writing is hard; but we can make it easier!
