@yimbydenver.bsky.social do you know if the gubernatorial debate this Saturday is going to be live streamed?

Great retrospective from Hadley:

Line chart titled ‘Weekly Runs of RStudio IDE’ showing usage data from 2023 to 2025. The y-axis ranges from 2,000,000 to 6,000,000 weekly runs. The chart displays a cyclical pattern with regular peaks around 5,000,000-6,000,000 runs and dramatic drops to approximately 2,000,000 runs that occur periodically during holiday periods.

Is #rstats dead? I don’t think so.

Netflix got the rights for 'Sesame Street'. New episodes later this year.

The hex sticker for the chores package: A cartoon illustration of a light orange potato character with rosy cheeks, holding a clipboard with a checklist in one hand and several small cards in the other. The potato is set against a purple hexagon outlined in a lighter orange. The word 'chores' is written diagonally in white in the upper right of the purple hexagon.

Introducing chores, a package that uses LLMs to help with repetitive, hard-to-automate coding tasks!

Manage prompts as markdown, select a chore, and let LLMs handle your tedious #RStats work.

Reviewer notes: That’s a very nice mediation analysis you have there. It would be a shame if something happened to it. Mediation analysis has gotten a lot of flak, including classic titles such as “Yes, but what’s the mechanism? (Don’t expect an easy answer)” (Bullock et al., 2010), “What mediation analysis can (not) ...

New blog post! In which I explain the issue with mediation analysis and sketch out one way to deal with the underlying causal inference problem -- in just a bit over 1,000 words!

Air, an extremely fast R formatter We are thrilled to announce Air, a new R formatter.

@lionelhenry.bsky.social and I are so excited to finally announce Air - an extremely fast R code formatter! 🎉

With Air, you'll never need to worry about styling your #rstats code ever again. All you need to do is save, and Air takes care of the rest.

The latest release of the {mvgam} #rstats 📦 has hit CRAN. Plenty of exciting new features including Joint Species Distribution Models, support for the full range of Gaussian Process kernels available in the {brms} 📦 and plenty more nicholasjclark.github.io/mvgam/news/i...

Fun little #rstats thing I've been doing with {targets}—you can use the {cli} package (cli.r-lib.org) to add nicely formatted messages to your targets pipeline output, like the "Website uploaded…" message here with cli_alert_success()

Works for anything, really, not just {targets} things

Should I talk to Jack about getting access to the data? I was looking through the paper this past weekend and trying some different things with what they published in the paper. Interested in what the permitting nums look like for the other hoods, e.g. shadyside, squirrel Hill.

Stats and Urban Econ Notes - New Updates An easier way to get updates on stats and built environment ideas

New quick review on Alain Bertraud's "Order Without Design" and sharing my notes on
@tslumley.bsky.social's excellent survey book and #rstats software.

The zoning process is more than just a map & a code. Many projects require special hearings & city council review.

In new research @urbaninstitute.bsky.social, I show that in Chicago, 58% of permitted housing units undergo that sort of discretionary review.

YouTube video by Posit PBC Tidymodel prediction workflows inside databases with orbital and Snowflake

At posit::conf(2024), we introduced the orbital package, allowing you to seamlessly translate tidymodels workflows into SQL backends.

Nick Pelikan walks through an end-to-end tidymodel prediction workflow using orbital and Snowflake, now available on YouTube!

Highways are really awful barriers to the urban fabric, as we can all intuitively grasp

A cool paper this year used smartphone data to show that highways create a meaningful distortion in how people move around cities, especially for non-work trips

If you're interested in trying out LLMs in #rstats but don't know where to begin, I've added a few two vignettes to elmer: elmer.tidyverse.org/articles/elm... and elmer.tidyverse.org/articles/pro...

Does #randomization ensures balance of risk factors between groups? Consider this:

In Denmark 860 individuals were randomly allocated to either intervention or control. Individuals were unaware of their allocation. No intervention took place. Mortality was higher in the intervention group (p=0.003)

Could you share the source? Always trying to find data for these things
