wbw {cenROC} | R Documentation |
Function to select the bandwidth parameter needed for smoothing the time-dependent ROC curve.
Description
This function computes the data-driven bandwidth value for smoothing the ROC curve. It contains three methods: the normal refrence, the plug-in and the cross-validation methods.
Usage
wbw(X, wt, bw = "NR", ktype = "normal")
Arguments
X |
The numeric data vector. |
wt |
The non-negative weight vector. |
bw |
A character string specifying the bandwidth selection method. The possible options are " |
ktype |
A character string indicating the type of kernel function: " |
Value
Returns the estimated value for the bandwith parameter.
