R Question

CI of PPV and NPV using pROC

I've been using the

pROC
package in R to generate bootstrapped confidence intervals for SP and SN values corresponding to specific thresholds. However, I've been unable to find a way to generate CI's for PPV and NPV values. Does such a function exist inside
pROC
?

Answer

Yes, you can use ci.coords. Type ?ci.coords for more information.
