conf.fbroc.roc {fbroc} | R Documentation |
Calculates confidence intervals for the TPR at different FPR values or vice versa. The stepsize at which the TPR or FPR is calculated can be set as needed.
## S3 method for class 'fbroc.roc'
conf(roc, conf.level = 0.95, conf.for = "tpr",
steps = 250, ...)
roc |
Object of class |
conf.level |
Confidence level to be used for the confidence intervals. Defaults to 0.95. |
conf.for |
Use "tpr" to get confidence regions for the TPR at specific FPRs. Use "fpr" instead for confidence regions for the FPR at specific TPRs. |
steps |
Number of discrete steps at which the requested rate and the confidence region is calculated. Defaults to 250. |
... |
Further arguments, that are not used at this time. |
A data.frame containing either discrete TPR steps and estimates and confidence bounds for
FPR or vice versa, depending upon conf.for
.
