Dear All,
I have a confusing doubt in my mind. ROC curve for 3x3 or 2X3 table is possible?
If so,
1. Can any one please give some example and the hypothesis statements?
2. how the ROC curve will be in that case?
3. Stata codes for that ROC curve
In my case, I have blood sugar level (test) comparison with HbA1c (gold standard) in 3 categories like "normal" "Pre-Diabetic" and "Diabetic".
Please let me know the answer for the above mentioned questions.
Thanks a lot in advance.
