Investigation of Diagnostic Test Performance Using Receiver Operating Characteristic and Fundamental Concepts of Information Theory

Aims: Receive Roperating Characteristic (ROC) curveanda fundamental concept of information theory is directly applicable to evaluation of diagnostic test performance. In this study,the performance of the two diagnosis tests on the field of rheumatic disorder is analyzed byusing receiver operating characteristic and fundamental concepts of information theory. The aims of this study to investigate which diagnosis tests has better performance and to demonstrate which test can be an alternative to gold standard test by carrying out ROC and fundamental concepts of information theory. Study Design: ROC analysis and application of fundamentals concept of information theory
