fixest v0.13.0 is finally out!

It's still about making OLS and GLM estimations easy.

Some major changes:
- *default* VCOV becomes iid always!
- singletons are removed by default!

See all the changes here:

fixest: Fast Fixed-Effects Estimations

Fast and user-friendly estimation of econometric models with multiple fixed-effects. Includes ordinary least squares (OLS), generalized linear models (GLM) and the negative binomial. The core of the p...

jokes aside, it's really stg I'd like to implement

Laurent Bergé @lrberge.bsky.social · 7d

It will come some day: you just have to make amz pay me haha

Laurent Bergé @lrberge.bsky.social · 7d

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 😅

Laurent Bergé @lrberge.bsky.social · 8d

Haha Grant, you couldn't wait for the fixest update :-)

Beginning of the week CRAN's fixest version will have a brand new citation :-)

#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

Dang what's that accent?! First time I'm submitting to arxiv... there's a learning curve 😅

thanks :-)

Fast and user-friendly econometrics estimations: The R package fixest
By Berg\'e, Butts, McDermott

fixest is an R package for fast and flexible econometric estimation, providing a comprehensive toolkit for applied researchers. The package particularly excels at fixed-effects estimation, supported by a novel fixed-point acceleration algorithm implemented in C++. This algorithm achieves rapid convergence across a broad class of data contexts and further enables estimation of complex models, including those with varying slopes, in a highly efficient manner. Beyond computational speed, fixest provides a unified syntax for a wide variety of models: ordinary least squares, instrumental variables, generalized linear models, maximum likelihood, and difference-in-differences estimators. An expressive formula interface enables multiple estimations, stepwise regressions, and variable interpolation in a single call, while users can make on-the-fly inference adjustments using a variety of built-in robust standard errors. Finally, fixest provides methods for publication-ready regression tables and coefficient plots. Benchmarks against leading alternatives in R, Python, and Julia demonstrate best-in-class performance, and the paper includes many worked examples illustrating the core functionality.

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.

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!
