🚨 Disease modelers: Do you use empirical VE estimates interchangeably to inform vaccine effect parameters? Me too, and it’s distorting our predictions. VE estimates often do not align with model parameters. We discuss these pitfalls & solutions in our new preprint: arxiv.org/abs/2605.18571 🧵👇

Models can be powerful tools to study associations in data. But do they reliably reveal the truth? 🚨 In our new study, @danlarremore.bsky.social and I show that the model used to estimate VE from test-negative designs (TNDs) may not translate to other correlates of risk. doi.org/10.1093/aje/...

#rstats Please welcome Jarl, a new R linter. Jarl is a CLI tool with extensions in VS Code, Positron, and Zed. It can check thousands of lines of R code in milliseconds. Jarl provides several output formats, a Github Actions workflow, and more. Blog post: www.etiennebacher.com/posts/2025-1...

Celebrating the publication of our big collaborative spatial-social meta-analysis of density-dependent transmission effects, out now in Nature Eco Evo! doi.org/10.1038/s415... (or rdcu.be/eD6eB)

🚀 gratia 0.11.0 is out! Now has a paper in JOSS — please cite 📄 doi.org/10.21105/jos... Experimental parallel processing ⚡ New assemble() for building plots 🎨 Better support for complex families + new diagnostics 🧪 Lots of bug fixes + polish ✨ 👉 gavinsimpson.github.io/gratia/ #Rstats

The "reproducibility crisis" in science constantly makes headlines. Repro efforts are often limited. What if you could assess reproducibility of an entire field? That's what @brunolemaitre.bsky.social et al. have done. Fly immunity is highly replicable & offers lessons for #metascience A 🧵 1/n

All my ecology peeps slinging the GAM(M)s might find this paper interesting. I was surprised to learn there is a frequentist interpretation of GAM(M)s! (jk) besjournals.onlinelibrary.wiley.com/doi/full/10....

This rocks

New paper out yesterday on surveillance of the JN.1 variant of SARS-CoV-2 in France last year. Nice collaboration between private and public partners from public health and research! www.eurosurveillance.org/content/10.2...

Spotted traveler-based genomic surveillance at Newark airport! I freaked out over how cool they were while my family gave me weird looks…..

Thrilled this work is out! Truly a team product and a labor of love from all involved. www.cdc.gov/mmwr/volumes...
