Sample size for prediction model research
Prof Richard Riley provides the following talk on "Sample size calculations for clinical prediction model research (goodbye rules of thumb)" in the following short (~16min) video.
An extended talk, covering both development and validation situations, was given to the MRC Biostatistics Unit, Cambridge, entitled "PROGRESS in sample size calculations for clinical prediction model research" and is available to view here. And a workshop talk on the topic is given here. Related papers are shown here.
Lucinda Archer gave the talk "Minimum sample size for external validation of a clinical prediction model with a continuous outcome" for the MEMTAB 2020 conference, as follows. The corresponding paper is now published (PDF):
