Many are aunder the curve values

Description

Many are aunder the curve values.

Usage

colaucs(group, preds)
auc(group, preds)

Arguments

group

A numerical vector with two values, one of which must be strictly 1.

preds

A numerical matrix with scores, probabilities or any other measure. In the case of auc this is a vector.

Details

The AUCs are calculated column-wise or just an AUC if the vector function is used.

Value

A vector with length equal to the number of columns of the "preds" argument. The AUC vlaues for each column. If the "auc" function is used then a signle number is returned.

Examples

## 200 variables, hence 200 AUCs will be calculated
x <- matrix( rnorm(100 * 200), ncol = 200 )
ina <- rbinom(100, 1, 0.6)
system.time( colaucs(ina, x) )
a <- colaucs(ina, x) 
b <- auc(ina, x[, 1])
x <- NULL
