I have calculated sensitivity, specificity, PPV, NPV, LR(+), and LR(-) for the test below. My question is how to describe the test, i.e. good/bad, any features to notice? Condition Present Condition Absent Total Test + 83 8 91 Test - 6 22 28 Total 89 30 119 Sensitivity = 0.93 Specificity = 0.73 PPV = 0.91 NPV = 0.79 LR(+) = 3.44 LR(-) = 0.095

For a person selected at random, compute the following probabilities: (a) P(+ condition present); this is known as the sensitivity of a test. (b) PC- I condition present); this is known as the false-negative rate. (c) P(- I condition absent); this is known as the specificity of a test. (d)...
