@aboyle57 thx for the request. Is this something for the logistic regression or binomial test (binary outcome)? Can you add details / papers / R-Packages?

aboyle57 commented 1 month ago

@tomtomme Thanks Thomas. The package that's been used in R is pROC. https://cran.r-project.org/web/packages/pROC/pROC.pdf

Does that help? It has script for Youden index within it.

@aboyle57 Thx. I see, this is then for the binary classification module, as you requested. The paper is certainly helpful.

@tomtomme Great. Do you think it's something that could be incorporated? It would be a neat addition to the ROC curve section.

I tried to run the R script in the R module within JASP but I couldn't get it to work, presumably because that functionality doesn't exist!
