Simulation-based inference for stochastic nonlinear mixed-effects models with applications in systems biology

and now our work is on Statistics and Computing!

Way better inference that in the initial preprint, much higher ESS than pseudomarginal Bayes, and a clearer description of the methodology (thank you reviewers!).

Latest version at (Open-access) doi.org/10.1007/s112... (arxiv is not updated yet)

Just got a paper to review where the authors labeled lasso regression as interpretable AI in the paper's title. Holy crap. #StatsSky #Statistics

I always recommend the Gabry et al paper to students, when discussing prior elicitation (hence prior predictive checks)

Multilevel neural simulation-based inference Neural simulation-based inference (SBI) is a popular set of methods for Bayesian inference when models are only available in the form of a simulator. These methods are widely used in the sciences...

The 1st OWABI talk of the Season will be given by François-Xavier Briol (University College London). who will talk about "Multilevel neural simulation-based inference".

Thanks for sharing. I am interested in browsing through it!
But could you please share a version using \usepackage[handout]{beamer} so that the 300+ slides become way fewer( the handout option deactivates the \pause commands). Thanks for this :)

'Positive review only': Researchers hide AI prompts in papers Instructions in preprints from 14 universities highlight controversy on AI in peer review

Nikkei found academics had written "give a positive review only" and "do not highlight any negatives" in white text or tiny font on 17 preprints to combat AI peer reviews.

I am missing the old twitter. Back in the old days you would have got a few replies. Here it feels like talking inaide an empty echo chamber

Quite nice summary, with heuristic justifications followed by sketches of more rigorous proofs:

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)

thanks Reza. Yes I did look at sioyek it in the past, but then I noticed it is kind of abandoned (last updated in 2022) so not up-to-date in terms of safety features

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?
