Hoy se celebra el Día Pi al ser 14 de marzo (es decir, 14/3 o 3/14 para los estadounidenses 🙃 ) También se celebra el Día Internacional de las Matemáticas. Así que celebrémoslo con una simulación mítica ya: cómo aproximar el valor del número Pi simplemente tirando bolitas dentro de un cuadrado 👇

Data labelling in R!

The R for the Rest of Us podcast is BACK! Mike Stackhouse from Atorus Research joined us for a chat about using AI with R effectively & safely. He gave a live demo creating clinical reports from scratch, demonstrating how to build reproducible analyses. Learn more: buff.ly/xPl00FL #Rstats #AI

Why are people across the world having fewer children, and can immigration solve the workforce problem this creates? @berkayozcan.bsky.social in an interview @lseeuroppblog.bsky.social

In this edition of the @posit.co AI Newsletter, we share about new LLM features in RStudio, some vibe checks on the new GPT 5.4 / Qwen3.5 / Gemini 3.1 Flash-Lite releases, and an overview of the Anthropic / Pentagon saga. Read it here: posit.co/blog/2026-03...

I love me some Bluesky, but I can't help feeling this place has largely died as a forum for economists. Meanwhile it seems like econ discussion on the other site has made a comeback. How are others feeling about this?

We had a #DSLab walking through using the {mall} pkg + {ellmer} in #rstats (& chatlas in #python) to process text columns in a dataframe with LLMs. This is something I find super helpful, esp when the task is tedious, big, & only needs to be done once, then reviewed. #databs youtu.be/ZNHNVWUMTJA

I've got to say no no no #RStats

"We used a very common statistical procedure and applied functions from standard R packages" really is not a reason for not publishing the code.

Alright class, #rstats #dataabs, a question, and this will be on your exam: Code quality, in particular readability, and the management of complexity is *much* more important in data analysis than software engineering in general. Why?

“el comercio internacional no es una guerra de países, sino un mercado gigantesco donde las empresas y los consumidores hacen lo mismo de siempre: vender, comprar y organizarse lo mejor que pueden. Es una liga en la que todos pueden ganar algo.”

Desgraciadamente, importantes partidos y medios de comunicación continúan dando eco y espacio a la idea de que la inmigración trae crimen. ¿Pero qué dice la evidencia? A esto respondo en mi nueva entrada en @nadaesgratis.bsky.social nadaesgratis.es/santiago-san...

Trends and random walks in macroeconmic time series : Some evidence and implications by Nelson, Charles R. & Plosser, Charles I. (1982)

Charles Plosser, RIP - Marginal REVOLUTION

Charlie Plosser served as a faculty member and Dean of the Business School at the University of Rochester. He served as editor of the Journal of Monetary Economics (with Bob King), and later the President of the Philadelphia Fed. A serious and sensible economist. RIP.

Charles I. Plosser passed away on August 14, 2025. Here is an obituary www.hoover.org/profiles/cha... Among his many influential academic contributions, one might mention "Real Business Cycles" (1983, together with John B. Long). people.bu.edu/rking/EC702/...

After I set up a Python environment to run LLMs locally with Docker Model Runner, I wondered if you could use the same workflow with R. The short answer is, "Hell Yeah!" It took me 5 minutes to run LLMs with R using the ellmer library. Working on a step-by-step tutorial... #RStats #LLM #Docker

I often need to filter data in #rstats based on many variables. The dplyr::if_any() and dplyr::if_all() functions are really handy for this. More examples here: cghlewis.github.io/data-wrangli...
