I have found a great new #stats teaching hack to find new open datasets for teaching. I've been going to the Collabra: Psychology journal website, and typing in an analysis type (e.g., logistic regression) into the search bar. Both quick and high-quality data! online.ucpress.edu/collabra

I ignored the strip.clip argument in #ggplot2 for way too long 😲 Combined with a small negative margin tweak, you can place facet labels inside each panel. A tiny trick that makes small multiples feel so much cleaner. 🔵 no manual coordinates 🔵 inherits theme styling 🔵 scales nicely when resizing
Side-by-side comparison of two multi-panel bubble charts faceted by world region. The left column shows the default facet labels placed above each panel (“Africa”, “Americas”, “Asia”, “Europe”, “Oceania”). The right column shows the same charts, but the facet labels are moved inside each panel at the top-left using a negative margin. In the center, there is a title reading “Want to place your facet labels inside each panel?” with an arrow pointing right, followed by a short ggplot2 theme code snippet demonstrating how to move strip text inside the panel.

After two weeks, I'm finally done! In this post, I explain different approaches for solving linear regression in R: directly, using QR, singular value and Cholesky decompositions, and do some benchmarking for comparison with in-built approaches. thomvolker.github.io/blog/2506_re...

Good Science xkcd.com/3101/
5-panel comic. (1) [teacher with long hair next to whiteboard] TEACHER: I’m supposed to give you the tools to do good science. (2) [teacher addressing students] But what *are* those tools? Methodology is hard and there are so many ways to get incorrect results. What is the magic ingredient that makes for good science? (3) TEACHER: To figure it out, I ran a regression with all the factors people say are important: [embedded list in sub-panel, cut off at end] Outcome variable: correct scientific results. Predictors: collaboration; skepticism of others’ claims; questioning your own beliefs; trying to falsify hypotheses; checking citations; statistical rigor; blinded analysis; financial disclosure; open data (4) TEACHER: The regression says two ingredients are the most crucial: 1) genuine curiosity about the answer to a question, and 2) ammonium hydroxide. (5) STUDENT: Wait, why did *ammonia* score so high? How did it even get on the list? LONG HAIR: ...And now you’re doing good science!

Psych. Science just published a paper showing that the "warm glow" of donations can reduce depressive symptoms (d = [0.19, 0.46]). Most impressively, "micro" donations (one Chinese cent, or $0.0014) appear sufficient to trigger these large effects. Big if true? Let's dive in.
