We are very happy to publish the "National Elections Database," including the results of 1,023 presidential and 2,962 parliamentary elections conducted worldwide since 1946! www.nationalelectionsdatabase.com with Benjamin Marx and Vincent Rollet

Happy 10 year birthday to Science Advances! Had fun writing this up with our editor, Laura Remis. @science.org www.science.org/doi/10.1126/...

538-style poll collection has now been recreated by a small group of fans and former staff. all fully transparent and public now. return of live public aggregation is imminent docs.google.com/spreadsheets...

I got laid off today, with the rest of 18F. 18F was an elite federal software shop. We made gov't websites work better, more efficiently for the American people. We saved taxpayers from getting screwed over by contractors. And were fired for it. We made this website to tell our story: 18f.org

#UMISR: Preserve At-Risk Government Data! DataLumos, an open-access archive at ICPSR, is working to preserve/share critical govt data. Help keep the data accessible. Donate: datalumos.org Explore & contribute: myumi.ch/egrbW Volunteer: [email protected] #DataPreservation #SocialScience

Rdatasets is a collection of 2300 free and documented datasets in CSV format. It's a great resource for teaching and exploration! The new `get_dataset()` function from the {marginaleffects} 📦 allows you to search and load them directly in #Rstats. vincentarelbundock.github.io/Rdatasets/ar...

All - @science.org now has a @bsky.app share button! Enjoy!

If you have an issue where Dropbox is constantly syncing while @posit.co #RStudio is open, one solution is to run the following code in Terminal: find "Dropbox" -type d -name ".Rproj.user" -print0 | while IFS= read -r -d $'\0' folder; do xattr -w com.dropbox.ignored 1 "$folder"; done #rstats

Last week, Jacob Morrier and I presented about work that dramatically speeds up probabilistic record linkage using GPU acceleration. Documentation and code for Fast-ER is available, fast-er.readthedocs.io/en/latest/ But better yet, watch the video! youtu.be/wsv__0a_KDY?...

Voters are mostly partisans who rationalize, swing voters are often ignorant and voters project their views onto their candidates. But this has always been true! The media was better once, but there was no golden age. Most of their grandparents did not read Walter Lippmann's column.

Very nice example of how useful comparison (or trend calculation) usually needs something more than coefficients. They have a nice page on the general idea that is hidden down in the thread: ourworldindata.org/age-standard...

I'm teaching a grad seminar this winter on Prediction for Decision-making. We'll look at what it means to make good predictions for decision-making from various angles, with a focus on decisions for & about people. Reading list: statmodeling.stat.columbia.edu/2024/12/06/n... Suggestions welcome!

Our JSS article is out! And now I get to focus on {marginaleffects} 1.0.0. Stay tuned. www.jstatsoft.org/article/view...

This is good advice. People with stable handles, bios, and a post or two present well to would-be followers. Consider also a photo or thoughtful logo of yourself.

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...

Boosting Anton's starter pack to #StatsSky and #polisky. Lots of people worth following here. bsky.app/starter-pac...

Great to see @aleximas.bsky.social and gang of coauthors measuring salience *independently of choice* with an early well-trained algorithm (from @caltech.edu btw) that predicts visual attention for any image (a la Li and me QJE academic.oup.com/qje/article-...)

After a review process so long and intensive that the title changed twice, I'm excited/relieved that "How to Distinguish Motivated Reasoning from Bayesian Updating" is accepted at @polbehavior.bsky.social. osf.io/preprints/os... Here is how it's relevant for your Thanksgiving dinner 🦃👇

How does Approximate Bayesian Computation *ABC) work? @rabaath.bsky.social has a classic nice simple intro the ABC using the problem of infering the number of socks in a sample of laundry. There's a movie and a page with all the code. www.sumsar.net/blog/2015/07...

Yes, it was an anti-incumbent environment, *globally*—but the US had weathered the pandemic economy so much better than everywhere else, it was totally reasonably to think that the incumbent party could prevail. It was not a forgone conclusion. It was close, but still decisive against incumbents.

Now that @jacksonmatthewo.bsky.social has arrived, it’s a real network

Since it is inefficient to attempt to educate every reviewer individually, I am yeeting into your feed this clear paper from Gelman, Hill, and Yajima on how Bayesians can do even better than correcting for multiple comparisons. arxiv.org/abs/0907.2478

I'm writing up a brief history of the tidyverse? What do you want to know about it? #rstats

Put together a quick starter pack for political methodologists (broadly defined) who have made their way over to BlueSky. If I've missed folks, please let me know! go.bsky.app/JBavA7x

OpenElections update: we've posted official precinct results data for 17 of Michigan's 83 counties (20%) and will continue to keep rolling. You can help and we can get you started! github.com/openelection...

Now that I seem to have gotten new followers interested in my editor takes, If you're asked to do a referee report and you're not sure if you have enough time, just quickly reply to the editor that you don't have time. Do not let the request languish. Ghosting a request is the worst option.

To celebrate Colin being on Bluesky (@cfcamerer.bsky.social), a reminder to submit to "Mindful Economics: A special issue in honour of Colin Camerer" at JEBO starting December 1 that Alex Brown, Ian Krajbich, Marco Palma, and I are guest-editing www.sciencedirect.com/special-issu...

AAAS would like to learn more about researchers’ experience with CC BY and other open licenses. What impacts have such licenses had on downstream uses of your research output? Scientists, please consider taking our short survey here: bit.ly/48iDDO7

Notes on Bluesky etiquette: - Likes are messages to creators that you like that thing. Send em a little happy boop. - Reskeets mean "I think other people should see this". - Reskeets are the best way to boost content -- likes don't generally make it into most feeds. - Don't be an asshole

Congrats @jnkatz.bsky.social ! www.caltech.edu/about/news/k...
