For me, this work is a classic @ohbmofficial.bsky.social story: In 2023 I wasn't working with @bttyeo.bsky.social but I overheard him at his poster pointing to some accuracy curves saying "I don't why they have this particular shape". That kicked off the collab that led to these results.
3/11 Tom's model explains empirical prediction accuracies well across 76 phenotypes from 9 resting-fMRI & task-fMRI datasets (R2 = 0.89), spanning many scanners, acquisitions, racial groups, disorders & ages.
Does this mean that we should collect large datasets with short scans?

Wasn't aware of tinyplot... an overlay package to make base R graphics easier to use. While I use ggplot2 for some tasks there are many situations where I prefer base R plotting, and this tool will be super helpful in those seetings.
`tinyplot` v0.4.2 is now available on CRAN + R-universe 🎉 Mostly bug fixes, but includes some important integration improvements for Positron IDE users. Release notes: grantmcdermott.com/tinyplot/NEW...
