Here we are for the North South Criminology conference! ☀️ Despite the unprecedented heatwave, there’s been some amazing speakers. #Criminology #Conference #ResearchWithImpact #TeachingAndLearning
I hope I’m not the only one dealing with endless (mostly AI) reviewer comments!!
I made a #Shiny app about post hoc power and effect-size uncertainty. If you accept an observed effect, you also need to accept its uncertainty. The app shows how power wobbles when you consider the CI, not just the estimate. Embrace the #wobble #samplesize open.substack.com/pub/mzlotean...
Power is wobbly, and 80% might be more like 5%
A Shiny app for showing that power analysis based on an empirical effect-size estimate is only as stable as the estimate itself.

Currently a lot of attention is going to get people to preregister, to check preregistrations, and noting deviations. But the most important step will be evaluating the impact of the deviations! There is almost no work on this. Good topic for a young metascientist!

The Perspectives on Scientific Error (#PSE8) conference was great - I will be coming back. It was nice meeting so many new people, and getting the opportunity to discuss statistical, philosophical, and meta-scientific issues of scientific error.
Insights from the #PSE8 conference Day 2: I was particularly struck by a presentation from Prof Leif Nelson on the detection of problematic data. I wonder how many of us have came across problematic papers - or datasets and don’t what to do!? #ResearchIntegrity #OpenScience
Insights from the Perspectives on Scientific Error (#PSE8) conference 🧵 Day 1: what a thought provoking morning. Replication remains one of the cornerstones of scientific progress, yet replication studies are still notoriously difficult to publish. Many never make it into print at all.
Everything is ready for the Perspectives on Scientific Error conference that starts tomorrow in Leiden! I look forward to hanging out with the mix of metascientists, philosophers of science, and statisticians! So many old friends will be there (and hopefully some new ones)! #PSE8
