Hi I am a urology researcher and we are comparing two methods for visualizing kidneys and evaluating them based on the number of calyces ( cavities within kidney) detected for each test.
Initially I thought to use sensitivity and specificity but there are several instances where one method missed several calyces. So, essentially I am wondering if there is a test that predicts how accurately one method is at detecting the total number of calyces within a region of the kidney.
For example: the reference method (true number) detected 8 calyces and the experimental method detected 5, so there are technically three false positives within that single patient sample. And my total sample is 54 patients. Is there a test I can use?
Dear Jacob
I don't think that Specificity can be applied here. Missing some calyces couldn't be in any way considered as a false positive result. It is a matter of defect in the accuracy. Although Sensitivity is not the proper method, but at least is more fitting than the specificity in your case. I hope you already found the proper method.
