Hi Assume that I want to compare two methods, say skinfold measurement and BMI, in how they classify subjects into four categories. In a 2x2 table I would simply calculate sensitivity and specificity and NPV an PPV, using the standard formulas, but can the same be directly applied in the 4x4 table? Or are other methods preferable?
