Plotting Receiver Operating Characteristics Surface with user-provided FPR, TPR & TDR
Description
The function plots the colored ROCS in 3 dimensions using the rgl utilities. It shades the FDR-controlled AUC in the FPR-TPR plain. The VUS of the surface and the FCAUC area are calculated.
Usage
rocs.fptp(FP, TP, TDR, FDR.cut = 0.2)
Arguments
FP |
Vector of false positive rate. |
TP |
Vector of true positive rate. |
TDR |
Vector of true discovery rate. |
FDR.cut |
The cutoff value of FDR, for the purpose of FCAUC cualculation. |
Details
The ROCS is the surface spanned by the TPR-FPR-TDR and its projection to the TPR-TDR plain. The vulume is between the surface and its projection on the TPR-FDR plain (i.e. the AUC of ROC).
Value
The volume under the surface (VUS) is returned.
