The canvas() function from the ggview R package is very useful for previewing/tweaking a ggplot into publication-ready format: it renders a plot "as it would appear if saved to a file with the specified dimensions".

I started making this R package 6 years ago. I finally have it in a state I'm happy with, thanks to Claude Code #Rstats github.com/MattCowgill/...

It would be a lot of fun to go full-on causal machine learning with this. If anyone would be interested, reach out to me! I am not be able to do it alone, given the deadline

๐Ÿ“ฃ Our introduction to structural causal models in science studies is now published:
doi.org/10.1162/QSS....

@tklebel.bsky.social and I tried to make our introduction as accessible as possible. We illustrate the theory by three case studies based on a simulated model of Open Science. ๐Ÿงต(1/6)

Identification and Scaling of Latent Variables in Ordinal Factor Analysis | Psychometrika | Cambridge Core Identification and Scaling of Latent Variables in Ordinal Factor Analysis

Researchers often treat ordinal variables as continuous. What if we could mimic this in an ordinal factor analysis/IRT model? We propose new identification constraints so that the latent variable goes from 1 to (# of ordered categories), with connections to treating ordinal variables as continuous.

Title page of syllabus: https://muellerstefan.net/teaching/2026-spring-qta.pdf

My updated syllabus for Quantitative Text Analysis is available online. As I previous years, I made quite a few changes and added recent literature. Part 1 (still) covers classic text-as-data approaches; Part 2 focuses on transformers and LLMs.

This paper had a pretty shocking headline result (40% of voxels!), so I dug into it, and I think it is wrong. Essentially: they compare two noisy measures and find that about 40% of voxels have different sign between the two. I think this is just noise!

How to Use Notion for Academic Research โ€“ Homepage I provide some advice for how to use Notionโ€™s powerful management software for the unique challenges of academic research.

Inspired by this post by @rmkubinec.bsky.social: What are your favorite project management tools for academic research? I mainly want to keep track of tasks and discussions, and I don't necessarily need file storage. So something that's free would be preferable. www.robertkubinec.com/post/notion/

Angry? Do something about it. Find & gather into a group of other angry people with the aim to collectively do something about it. Read some literature on What Is To Be Done & arm that anger with knowledge. Remain angry, but don't remain unmoved.

You either live in a democracy, in which case you, as citizens, are responsible for the actions of your democratically elected leaders...or you have no choice in who gets elected, in which case you don't live in a democracy and you should definitely do something about that.

The world is sick of hearing 350 million Americans say they're helpless and nothing is their fault

If "not untrue".... What's your point? If it's true then it's true. Trying to minimize the colonial history of USA is the problem. Maybe worth thinking twice what's on the line for all latin America, instead of debating if a true statement should be reposted.

The attack on Venuzela sovereignty is a straightforwardly condemnable act.

America is the thief of the world & the future. It is a bipartisan regime, built on indigenous blood & fueled by stolen oil. You pay taxes to rip apart countries for the sole benefit of CEOs & shareholders. Rip it up.

If you don't know why the map is reversed, you are also probably in an imperialist country. "Global south" etc. does not exist. Learn from Uruguay:

Did people skip the imperialism class? USA started this fascist project ages ago, and will probably continue this project with many other countries alongside them. Kick fascists in the mouth. Viva a Amรฉrica latina.

Two years ago, I had an idea, one that evolved over time as I kept reading and learning. Today, a major first part of that idea has just become my first PhD preprint, now publicly available on PsyArxiv.

Let me tell you a bit more about the story behind it... while I prepare the submission.
