NEW preprint 'Stability of prediction models' @Richard_D_Riley
arxiv.org/abs/2211.01061
Influenced by @f2harrell 'example models', different samples from a population to train models (small/mod. N) will lead to wildly different predictions for the same individual. #statstwitter

🌟NEW PREPRINT PAPER🌟
"Stability of clinical prediction models developed using statistical or machine learning methods"
- with @GSCollins
What is model (in)stability?
How do we examine, present & quantify it?
How does sample size impact (in)stability?

Our BMJ review of accuracy of apps that assess the risk of skin cancer - few published studies, many limitations, and cancers can be missed but users are not informed. Two apps have CE marks? Not safe! bmj.com/cgi/content/full/bmj… @UoB_IAHR @UoB_TERG @deeksj @NIHRBhamBRC @jessRmorley
