In cenROC: Estimating Time-Dependent ROC Curve and AUC for Censored Data
wbw 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 "NR" for the normal reference, the plug-in "PI" and cross-validation "CV".
ktype
A character string indicating the type of kernel function: "normal", "epanechnikov", "biweight", or "triweight". Default is "normal" kernel.
Value
Returns the estimated value for the bandwith parameter.
