Technical Report XIII
Calculator for Diagnostic Accuracy Measures
T Chatzimichail
Abstract
This Demonstration calculates various diagnostic accuracy measures of a diagnostic test for a disease. This is done for different numbers of negative and positive test results in nondiseased and diseased populations. The measures calculated are the sensitivity, the specificity, the positive predictive value (PPV), the negative predictive value (NPV), the (diagnostic) odds ratio (OR), the likelihood ratio for a positive test result (LR+), and the likelihood ratio for a negative test result (LR−). The negative and positive test results of the nondiseased and diseased populations are selected using sliders.
