This calculator helps answer questions like this:
"Assuming AUC = 0.9, how
many participants should be recruited to assure with 90% chance that the lower confidence
limit of the AUC is above 0.8?"
This calculator helps answer questions like this:
"Assuming my improved test has an AUC of 0.9 while
the standard test has an AUC of 0.7, how many participants should be recruited to assure with 90% chance that the lower confidence
limit of AUC difference is above 0.1?"
