Out now, with @jamiecummins.bsky.social & @uschroeders.bsky.social: why ML research benefits from Registered Reports, and where the format reaches its limits. Table 1 goes through 7 scenarios, from confirmatory prediction to climbing a benchmark leaderboard. Free view-only link: rdcu.be/MCamygrKHKxa

To help researchers in this respect, @uschroeders.bsky.social and I wrote a tutorial on sample size planning for IRT analyses (open access). It includes practical recommendations and R code examples in the supplemental material.
