Schuetz


  Data from Schuetz (2010) of the diagnosis of coronary artery disease (CAD),used conventional coronary angiography as the reference standard. Among the total 103 studies, 84 evaluated only the accuracy of CT, 14 evaluated only MRI, and 5 studies evaluated both.


datasets

This package allows doing meta-analysis for primary studies with classification outcomes in order to evaluate systematically the accuracies of classifiers, namely, the diagnostic tests. It provides functions to fit the bivariate model of Reitsma et al.(2005). Moreover, if the reference employed in the classification process isn't a gold standard, its deficit can be detected and its influence to the underestimation of the diagnostic test's accuracy can be corrected, as described in Botella et al.(2013).
