Is it possible to do a sample size calculation using the PLP package (as per the TRIPOD+AI guidelines https://www.tripod-statement.org/wp-content/uploads/2024/04/[TRIPODAI-Supplement.pdf](https://www.tripod-statement.org/wp-content/uploads/2024/04/TRIPODAI-Supplement.pdf)):
Explain how the study size was arrived at (separately for development and evaluation), and justify that the study size was sufficient to answer the research question. Include details of any sample size calculation
● Describe how the sample size was determined – this should be done separately for determining the sample size needed for model development and the sample size needed to evaluate the performance of the model irrespective of whether data are being prospectively collected or using existing data
● Provide details and all estimates used in any sample size calculation
I developed and externally validated a model using the PLP package and would like to include a sample size calculation in my write up of this project. I wanted to check if it would be possible to do this within the PLP package or whether I would have to do this separately?
Many thanks
