auc: AUC

In Atools: Atools

Description

Area under the ROC curve. Calculated in various ways. Fastest is auc(), currently set to aucRank(). RLoop() only supports oriented=FALSE

Usage

auc(...)

aucPROC(y, y.hat, oriented = FALSE)

aucWilcox(y, y.hat, oriented = FALSE)

aucRank(y, y.hat, oriented = FALSE)

aucRLoop(y, y.hat, oriented = FALSE)

aucRapply(y, y.hat, oriented = FALSE)

aucROCR(y, y.hat, oriented = FALSE)

aucHmisc(y, y.hat, oriented = FALSE)

Arguments

y.hat	numeric. risk between 0 and 1.
y	numeric. Status yes=1, no=0 or dead=1, alive=0.
oriented	logical. If FALSE (default) returned AUC always ≥ 0.5.
...	Pass arguments. If TRUE: Probability that higher y.hat correspond to higher y.

Value

numeric.

Examples

y.hat <- seq(0,1,length=100)
 y <- rbinom(100, size=1, prob=1-y.hat)

 aucRLoop(y=y, y.hat=y.hat, oriented=TRUE)
 aucPROC(y=y, y.hat=y.hat, oriented=TRUE)
 aucHmisc(y=y, y.hat=y.hat, oriented=TRUE)
 aucWilcox(y=y, y.hat=y.hat, oriented=TRUE)
 aucRapply(y=y, y.hat=y.hat, oriented=TRUE)
 aucPROC(y=y, y.hat=y.hat, oriented=FALSE)
 aucRank(y=y, y.hat=y.hat, oriented=FALSE)
