Evaluation of the accuracy of diagnostic tests (English)

The gold standard test is typically used for diagnosing diseases. However, due to various reasons such as cost, feasibility, and ethical issues, the gold standard test may not be feasible in certain situations. In such cases, other instruments or screening tools can be utilized to diagnose diseases. Nevertheless, it is crucial to compare these screening tools with the gold standard test and assess their accuracy before adopting them. In this article, we will use an example implemented using R programming to discuss how to evaluate the accuracy of diagnostic tests.
