"WebTwo basic measures of test accuracy, sensitivity and specificity, can be estimated from the values in Table 1. Sensitivity is the test's ability to detect the disease when the disease is present (i.e. Sensitivity (Se) =P (T+ D+) = n11 / n1) or, in words, the probability of a positive test result given that the disease is present.

Why is the mean of sensitivity and specificity equal to the AUC?

WebThe characteristics of a test that reflects the aforementioned abilities are accuracy, sensitivity, specificity, positive and negative predictive values and positive and negative likelihood ratios (9-11). In this educational review, we will simply define and calculate the accuracy, sensitivity, and specificity of a hypothetical test. Definitions: WebOr worse, we could improve overall Accuracy just by making the test more able to find the more common category. So a better approach is to look at the accuracy for Positives and Negatives separately. These two values are called Sensitivity and Specificity. Sensitivity = d/(c+d): The proportion of observed positives that were predicted to be ...
