We kick of the visiting speakers' research seminar today at @princeton.edu with @alex-andorra.bsky.social joining us for a talk and workshop on #BayesianWorkflow and AI-assisted statistical modeling. These sessions are open to the public on zoom. For details, see the flyer below!

Huge pleasure to host my friend Alexander Fengler on the show, to go through his latest work on #AmortizedInference and the power of the neural nets + Bayes combination!

Alexandre Andorra @alex-andorra.bsky.social · 01/09/2026
Today's episode is a #BayesianBlockbuster, where I talk with three of the most influential teachers of the #stats world... plus a surprise somewhere in the middle 😏 It was an absolute blast to record it -- I hope it'll be as good to listen to it for you!

🎙️ New episode! @alex-andorra.bsky.social sits down with Matthijs Hollanders on Bayesian occupancy models for wildlife data - what they are, why camera traps break classical approaches, and how his occARU R package handles it with hierarchical GPs and shrinkage priors. 🔗 lnkd.in/dw3WuMBg #bayes

Wrote up the full story behind the #CausalInference agent skill. Key insight: agents *know* causal inference, but they never stop to ask "is my DAG right?" or "does this survive a placebo test?" The skill doesn't add knowledge. It adds discipline. Full breakdown: learnbayesstats.com/blog-posts/c...

Just released a new #AgentSkill: causal inference that refuses to say "causes" until it's earned the right. DAG before data. Assumptions before estimates. Refutation before claims. 100% eval pass rate vs 68% without the skill. The gap is in the reasoning, not the code. 👉 github.com/Learning-Bay...
