I received a request to review from a top stats journal. It contained this (surprising to me) line: "If you cannot accept this invitation then it would be very helpful if you could suggest alternative referees (please include them in a reply to this email)." Anyone surprised about cc'ing referees?

Proud supervisor moment! Congratulations to Petar Jovanovski for successfully defending his PhD thesis "Simulation-based parameter inference methods based on data-conditional simulation of stochastic dynamical systems". 👉 interview with Petar with link to thesis (bottom) tinyurl.com/54b5bp4f 1/3

What is common knowledge in your field, but shocks outsiders? Nicolas Metropolis did not play any scientific role in the development of what is known as the "Metropolis" (and later Metropolis-Hastings) algorithm. (pic: the MANIAC computer that Arianna Rosenbluth used to code the algorithm)

Zotero's pdf reader is becoming my go-to choice. By hoovering the mouse on a citation, or any hyperlinked section/equation/table etc, a super handy window pops up. So no need to scroll through the pdf and interrupt the reading flow. Any other pdf reader (for Windows) with such feature?

Want to fit challenging stochastic models with mixed-effects? Check our new paper and the thread by @henhagg.bsky.social 👇 We construct an SBI framework to obtain expressive, parsimonious approximations of the likelihood and the posterior. The methodology is scalable and easily trainable.

New paper on SBI for stochastic nonlinear mixed-effects models! We propose a scalable Bayesian framework for hierarchical mixed-effects models, using amortized likelihood and posterior approximations, obtained without neural networks. 🔗 arxiv.org/abs/2504.11279

You publish papers in statistics journals and you're proud of them? But, when your friends ask "are you coming to AISTATS with us?", you feel sad and you regret not to submit papers to conferences? Well, this message is for you! There is now a Journal-to-conference track at #AISTATS2025!

Kamélia Daudel@kdau.bsky.social · last yr.

🚀 Excited to announce the launch of a pilot trial for the Journal-to-Conference track at #AISTATS2025, coordinated by @pierrealquier.bsky.social and me The track considers published papers from AoS, Biometrika, JASA, JMLR & JRSS B for a poster presentation at AISTATS 2025 📅 Deadline: 15 March 2025
