Last week I spent 3 days in Vienna for the @saa2026.bsky.social #SAA2026 I presented OMSS (incl. live demo: github.com/jorvlan/SAA2...) which is free Python software for reasoning items: pypi.org/project/omss/ And gave a talk with the first results from our CODEC study: doi.org/10.1186/s403...

I had such a blast presenting the last project of my PhD for a flash talk and a poster at #Flux2025 Grey and white matter are not two separate tissues and we found that adversity is associated significantly differently with grey and white matter measures showing the importance of looking at both!

The Raincloud Quartet (new pre-print) All N = 111, M = 0.04, SD = 0.27. One-sided t-tests vs. 0 yield: t(110) = 1.67, p = .049. Only raincloud plots reveal the qualitative differences, preventing the drawing of inappropriate conclusions. How did we create the quartet? Where are data & code? 🧵👇
Four raincloud plots: a normal distribution, bimodal, skewed, and one riddled with outliers. Popular sample statistics are identical so that mere plotting of the identical means and confidence intervals would miss these qualitative differences.abstract of pre-print
