adjROC
:
ROC Curve Evaluation at a Given ThresholdadjROC
is an R package for computing adjusted
sensitivity and specificity at particular thresholds. There are methods
for estimating the best balance betwen sensitivity and specificity.
However, in clinical settings, there might be an interest in calculating
the sensitivity based on a particular fixed value of specificity or in
contrast, calculating specificity for a particular value of sensitivity
which is of interest.
For a screening test, specificity of 0.95 might be too high and lower
values of specificity may also be acceptable. In another settings,
researchers might wish to know the mount of specificity, while keeping
sensitivity high. And finally, in some situations, a roughly equal value
might be desired. Depending on the application, adjROC
package allows users to calculate:
and on top of these, it can also visualize the curves and the selected cutoff threshold.
