WebOct 1, 2011 · Some properties of symmetric ROCs are discussed in Iverson and Bamber, 1997, Iverson and Bamber, unpublished. Johnson and Dudgeon (1993) have shown that in the binormal (equal variances) case when the ROC curve is symmetric, the two KLDs are also equal. However, not much is known beyond this in relation to symmetric ROC and … WebQ point in sROC is the point where the curve is intersected by a diagonal running from the top left to the right bottom corner of the sROC space and provides an estimate of composite ... A random-effects sROC model was employed to fit a single symmetric sROC curve because of the high degree of heterogeneity. The AUC for iFR was 0.8786 ...
