Relation of Diagnostic Accuracy Measures
T Chatzimichail, AT Hatjimihail
Abstract
This Demonstration examines the relation between pairs of diagnostic accuracy measures of diagnostic tests applied to normally distributed nondiseased and diseased populations. This is done for different values of disease prevalence, taking into account the means and standard deviations of the populations. The means and standard deviations are expressed in arbitrary units. The measures considered are 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 measures can be selected by selecting the respective 'plot' and 'versus' buttons.
