Can proc be used to compare smoothed ROC curves with partial AUC?
Using “delong” for partial AUC and smoothed ROCs is not supported in pROC and result in an error. It is spurious to use “delong” for roc with different direction (a warning is issued but the spurious comparison is enforced). “venkatraman”'s test cannot be employed to compare smoothed ROC curves, or curves with partial AUC specifications.
How do you test for a difference in ROC curves?
Delong and bootstrap methods test for a difference in the (partial) AUC of the ROC curves. The Venka-traman method tests if the two curves are perfectly superposed. The sensitivity and specificity methods test if the sensitivity (respectively specificity) of the ROC curves are different at the given level of specificity (respectively sensitivity).
What happens if ROC object is passed to Roc test?
Warning: if the roc object passed to roc.test contains an field auc and reuse.auc=TRUE, auc is not called and arguments such as are silently ignored. bootstrap replicates are drawn from the data.
What is the sensitivity of a ROC curve?
Since the sensitivity is defined as P (test>x)|status=TRUE P (test > x)∣status = TRU E, the first row has sens equal to 1 and spec equal to 0, corresponding to drawing the ROC curve from the upper right to the lower left corner.
