AROC (version 1.0-4)

paauccontrol: Partial area under the covariate-adjusted ROC curve (pAAUC).

Description

Used to set various parameters controlling the estimation of the partial area under the covariate-adjusted ROC curve (pAAUC).

Usage

paauccontrol(compute = FALSE, value = 1)

Arguments

compute

Logical value. If TRUE the partial area under the covariate-adjusted ROC curve (pAAUC) is estimated.

value

Numeric value. Pre-specified maximum false positive fraction (FPF) at which to calculate the pAAUC.

Value

a list with components for each of the possible arguments.

Details

The value returned by this function is used as a control argument of the AROC.bnp and AROC.bsp functions.
