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
1
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.
