🎉Congratulations to our graduates 2025! Forever Uni Bonn - Over 2,000 graduates celebrated the 20th anniversary of its Universitätsfest — with over 5,000 of their friends and family — a new record. Read more www.uni-bonn.de/en/news/20-j... (c) Marc John/Uni Bonn #UniversityOfBonn #ForeverUniBonn

Hi #EconSky! I will be teaching intro statistics with #rstats next academic year. Any suggestions for free learning resources for students and/or teaching materials?

Nice thread on simultaneous confidence bands (SCBs) by @noahgreifer.bsky.social ! Not many papers explore varying critical values—despite cool uses like narrower or fairer bands. Bit of shameless self-promo if you're into this 😉: academic.oup.com/jrsssb/artic... #econsky #statsky

Zwei auf einen Streich! 😊 #EconSky #rstats

🚨 Big milestone for Rdatasets 🚨 The web archive now hosts 3400+ free and documented CSV datasets. Fantastic for teaching and testing! And {Rdatasets} is a new #RStats 📦 for easy download and search Web archive: vincentarelbundock.github.io/Rdatasets R 📦: vincentarelbundock.github.io/Rdatasetspkg

Just learned something new. You can buy spurious citations that will show up on Google Scholar -- and people do.

From @newyorker.com

New working paper: "Testing the Missing Completely at Random Assumption for Functional Data," joint work with Max Ofner*, S. Hörmann and D. Kraus. As far as we know, it's the first paper on testing MCAR for functional data. *Look out for this smart guy.

Grace Wahba, "the mother of smoothing splines," won the International Prize (aka the Nobel) in Statistics #stats for her representer theorem. youtu.be/8Ae_QzwwR_U?... So well deserved! I guess, one could also give her the price again in two years for her work on Generalized Cross-Validation.

Hello world

Riesige Glückwünsche an Claudia Goldin zum diesjährigen Nobelpreis für Wirtschaftswissenschaften! Worum geht es bei ihrer Forschung? Ein paar Eindrücke aus ihrer Forschung zum Arbeitsmarkt (auf deutsch).

There is a new feature to show some posts from other feeds in your following feed. 📈📉

Teaching intro data science or stats in environmental sciences / ecology this fall? The lterdatasampler package is now on CRAN, with curated real world datasets from the US Long Term Ecological Research program! Check it out: lter.github.io/lterdatasamp...

I recently experimented with Quarto, the next-gen rmarkdown. It can be used to produce wonderful online lecture sites combining theory with R code. This is a refresher in matrix algebra for my econometrics students: matrix.svenotto.com

Why do academics throw all scientific standards out of the window as soon as the topic is “AI”?

Groundhog for R is so good for reproducibility. You just load your packages with it and voila, anyone who runs your script will have the same package versions. One less hurdle to reproducible code. Props to the team at Wharton Credibility Lab! groundhogr.com #psychscisky

Nice! 10 Fundamental Theorems for Econometrics and their proofs: #Econsky bookdown.org/ts_robinson1...

I have now my own #bsky handle that matches the web address of my homepage: @dliebl.com Works like a charm with the descriptions provided below: h/t @hannesullrich.com & @davidwalsh.name

Reposting for newcomers: you can kind of self-verify on Bluesky (and have a nicer handle). #EconSky If you have a domain where you can control the DNS entries (often the case if you have a domain forwarding to or hosting your personal website), follow the quite easy instructions in the linked post:

Mein Computational Statistics Kurs in diesem Semester wird sowas wie ein montägliches Stats-Bootcamp. Im besten Fall wird es ein großer Spaß. Aber wahrscheinlich werfen sie ihre Kaffeebecher nach mir.

New R/exams interface to "webexercises" pkg by @debruine.bsky.social & Dale Barr Embed #rexams exercises in static HTML, R/Markdown, Quarto, etc. Pkg still on R-Forge, replication code in alt text of first image. Try: www.zeileis.org/quiz.html #elearning #rstats
