I coded up an open-source, not-for-profit AI paper reviewer that rivals the performance of
@reviewer3com.bsky.social, Refine.ink, and Stanford Agentic Reviewer (according to Gemini 3.1). Costs <$2!
Live @ coarse.ink. Plug in paper, @openrouter.bsky.social key, and email. #econsky
This looks like a spectacular public good #econsky
(Full disclosure: @packlesshepherd.bsky.social is a co-author but my main skin in the game is maybe we'll finally finish our paper together now...)

arg! I wish R packages had better error messages!
Now they can, thanks to my newest #Rstats package, {arg}! 😉
{arg} produces clean, simple, error messages for checking function arguments, similar to {checkmate}, {dreamerr}, and {chk}, using {cli} formatting.
BTW, that's what {dreamerr} does.
It's just one function, the syntax is harder to learn, but is also quite powerful (see second example).
JUMPSCARE!
#RStats
I am very excited that PyFixest 0.50.0 is on PyPi, including a new graph-based solver for demeaning that makes fixed effects estimation in PyFixest significantly faster for "sparse" fixed effects structures.
Very excited for this Friday's Chamberlain Online Seminar, where we'll muse about "The Future of Econometrics." Check out this panelist lineup!
Friday 3/27 at Noon ET. Come see! t.co/pE1gZCMI7a
Hey #rstats & #econsky:
fixest v0.14.0 is out!
In particular, it fixes a very annoying, false positive, warning message regarding the positive definiteness of the VCOV (when clustered).
Please update!

jokes aside, it's really stg I'd like to implement
It will come some day: you just have to make amz pay me haha
kudos btw, it looks cool!!!! I love the :switch
With that project, I must say that my C++ skills and knowledge went to the roof... I thought I was decent in C++, but after that I realised how little I knew!
Were you good at Rust already? Did you see the same gains? It seems to me AI kills learning (for advanced K), but I may be wrong.
Gosh I've spent too much time developing one... I just should have waited 😅
#rstats I've been testing out `arf`, a new R console written in Rust. Early days, but a v. smooth experience so far. Much simpler to install and link from VS Code than radian, for example, with better features too. github.com/eitsupi/arf
Haha Grant, you couldn't wait for the fixest update :-)
Beginning of the week CRAN's fixest version will have a brand new citation :-)
Dang what's that accent?! First time I'm submitting to arxiv... there's a learning curve 😅
thanks :-)
One of the most important statistical packages made in Econ in the last decade
I'm excited to share the release and rOpenSci publication of dfms 1.0 (docs.ropensci.org/dfms), a high-performance, feature-rich implementation of Dynamics Factor Models for R, supporting mixed-frequency estimation and news decomposition for nowcasting. See also blog post: sebkrantz.github.io/Rblog/
Research Notes of the AAS in particular, which was set up to handle short, moderated contributions especially from students, is getting swamped. Often the authors clearly haven’t read what they’ve submitting, (Descriptions of figures that don’t exist or don’t show what they purport to)
Things are grim. But in more frivolous news...
@jamesbrandecon.bsky.social and I have been chipping away at `dbreg`, a 📦 for running big regression models on database backends. For the right kinds of problems, the speed-ups are near magical.

We are responding to this call for evidence:
ec.europa.eu/info/law/bet...
Do you have concrete examples of the added value of #Rstats in the public or private sectors?
Include the most important factors (risk, lock-in, security, innovation...) to assess the added value.
Thanks!
Cool project!
Soon we'll be putting an enclosure for our house: I'll ask you for tips!
Weekend thoughts on Gas Town, Beads, slop AI browsers, and AI-generated PRs flooding overwhelmed maintainers. I don't think we're ready for our new powers we're wielding. lucumr.pocoo.org/2026/1/18/ag...

Happy anniversary to my most successful tweet in 2020
The creator didn't like it :D

Félicitations!!! Je ne connaissais pas : c'est compliqué de postuler (je suis moi même contributeur) ?
Thanks for the resource: it looks very nice!
At the beginning of my teacher's career I taught mostly for the best students in the class.
As I get older, I can see I'm lowering my standards and teach more and more for the weaker students.
I also grade more generously as time passes.
=> is this a common pattern? Or is it just me? I'm curious.
Thanks! I knew the other but not this one! Good to know!
Thanks Alex, that's a great ref indeed!
Thanks for sharing!
