Few statisticians know that Frank Yates, pioneer of experimental design, is responsible for the annoying practice of indicating 3 tiers of statistical significance by stars (*p ≤ 0.05, **p ≤0.01, ***p ≤ 0.001). He soon regretted it and “vehemently opposed its unthinking use”. And here we are.

Huge thanks to @vdveenb.bsky.social & everyone who joined us for the GLLVMs in R course! 🌿 Bert’s expertise & clarity made complex topics accessible & engaging. Thanks for the great learning experience! Want to join us for the next edition? www.physalia-courses.org/courses-work... #Rstats
Day 2 of our #GLVMs in R course with @vdveenb.bsky.social is underway! Today we're exploring Joint Species Distribution Models for binary data, hierarchical environmental responses, species co-occurrence patterns, and predicting species richness and diversity from multispecies models📊 #RStats
The #GLLVMs in R with @vdveenb.bsky.social is almost full - last chance to join us next week! Thanks for spreading the word! www.physalia-courses.org/courses-work...

First time to #IAVS was a great succes! Even though Audun and I are not vegetation scientists, the atmosphere was very welcoming.
Probably one of the coolest presentation setups I've seen in a long time.
For those who missed my talk at #IAVS2026. Here it is all online: 🔗https://ondrejmottl.github.io/BIODYNAMICS-vegetation-cooccurrence/Documentation/Website/outputs.html Rendered slides: 🖼️https://ondrejmottl.github.io/BIODYNAMICS-vegetation-cooccurrence/Documentation/Presentations/IAVS_2026/_output

Come join me at #IAVS2026 today for my talk (LT4) 📅 11:30 (after coffee break) room 3. I promise you haven't seen #presentation like this one before😉 #vegetation #paleo #jsdm #conference @iavs5.bsky.social
We are in Gijon for #IAVS2026 representing @sciencecharles.bsky.social and @cts.cuni.cz Research of our Lab. of Quantitative Ecology () can be seen as my talk (LT4) and poster by @natynamesna.bsky.social (P111). Come to talk to us! 🔗 bit.ly/CUNI_Quantit... #LoQE #conference
Ik stel je verhalen eigenlijk altijd op prijs @chrisklomp.nl, maar zullen we autisme niet tot diskwalificatie degraderen?
Nieuw verhaal: chrisklomp.nl/kafka-bek-al... de praatzieke kleuter in een mannenlijf rapper Kafka blijft laster verspreiden. Dus is het tijd om even te reageren. Een stuk over een 'man' met een bek als een scheermes, maar ballen van bordkarton. En zijn vele leugens.
What is the replication crisis? Is it a problem in Ecology and Evolution? Can journals help us fight it? I'll be answering all these questions and more later this week in a free and open @sortee.bsky.social webinar. Come along to find out more!!
For the June edition of the SORTEE workshop and webinar series, Dr. Joel Pick (@joelpick.bsky.social) will join us at 13:00 hrs UTC on June 25th to discuss the role of journals in fighting the replication crisis ✨ Sign up at: events.humanitix.com/webinar-what...
Come and learn about advanced community data avalysis via model-based ordination and Joint Species Distribution Models with me 😀 github.com/BertvanderVe...

Good morning everyone ☀️ Take a look at our full list of courses running in July—there are still a few seats available! www.physalia-courses.org/courses-work... #Bioinformatics #Genomics #RStats #DataScience
Today we are running our AI-assisted Coding Workshop at Nord University in Bodø (Norway)! We couldn’t ask for a better setting: an amazing location, inspiring surroundings, and excellent infrastructure for learning and collaboration.
🌿 Early‑bird registration is now open! You can now register for the joint NSO–GfÖ 2026 conference at the early‑bird rate from 15 June-17 July. After this, the full fee applies until 16 Aug 2026. 🔗 Website: vist.ly/57ri8 #NSO2026 #GfOe2026 #NSO‑GfÖ‑conference
It hit me that we can con gllvm into facilitating gllvm::glmmVA with mixed response types, in a way that is akin to how to handle these things with INLA (look @bobohara.bsky.social, putting your wisdom to work!), which I think allows you to fit the random effect structure below?
@vdveenb.bsky.social where is the best venue for asking `gllvm` questions? Wanted to see if I could use the devel version to fit a multitype model equivalent to the following MCMCglmm specification (i.e. two different 'rows' grouping variables, each with random slopes) @idworkin.bsky.social ...
Oooh, look at this @bobohara.bsky.social
new diamond open-access Journal of Statistical Ecology launched 🎉🎉🎉 jse.centre-mersenne.org @fredbarraquand.bsky.social @oaggimenez.bsky.social @marieaugermethe.bsky.social @vianeylb.bsky.social (apologies to any Bsky editors I missed)
Apparently navigating the ordination minefield is easier than getting AI to reproduce my face.

At #NSO2026 @nordicoikos.bsky.social I will give a workshop on improved prediction of species richness with #gllvm. I will present background theory to explain why this is better than your typical log-linear regression of richness, which will be accompanied by a paper later in the year.
Hi #stats folks! Curious about how GAMs work behind the scenes? I've put together a shiny app to demonstrate how changing the coefficients for basis functions for a smooth affects the final fitted smooth and the penalty. Looking for any feedback on the UI! 206.12.100.5/gam-basis-de...

Closing the Generalised Linear Models in R course, with a look at powerful extensions of GLMs such as GAMs and GLMMs. A big thank you to @vdveenb.bsky.social for delivering another outstanding edition of the GLMs in R course! www.physalia-courses.org/courses-work...
Thinking about how this might go Listener: My chains aren't converging Andrew: Your model is bad Aki: Your parameterization is bad Richard: The Buddha teaches us that numerical integration is suffering
🚨 @rmcelreath.bsky.social @statmodeling.bsky.social & @avehtari.bsky.social are coming on the show mid-June to discuss their new book, Bayesian Workflow! ONE listener gets to bring a real Bayesian problem onto the recording and have the three of them work through it live. Here's how to enter 🧵
The 3rd edition of Generalized Linear Models in R, led by @vdveenb.bsky.social is now officially underway All the info here: www.physalia-courses.org/courses-work... #GLMs #Rstats
FWIW this is for this: lme4.r-universe.dev/lme4/doc/glm... ; companion to Bates et al 2015 JSS lmer paper, which fell through the cracks for 10 years. Not too much new here (IMO), but it's the reference document for the implementation of glmer(). (Available as a vignette in dev version.)

Reptiles with longer Wikipedia pages tend to be bigger. The relationship is a power law with exponent = 0.85. I guess humans really like writing about big lizards? The longest article is the Komodo Dragon.
@bobohara.bsky.social just tagged you on LinkedIn in something.
I've had quite a few review requests on ordination come in lately; three this week alone. I decline not because I don't want to review, I actually do. I always feel guilty turning down perfectly reasonable requests. Except the ones that misspell my name. Reviewer 2 can deal with those.
