Calculate ROC Statistics

Description

Calculates ROC statistics for a set of classes and their probabilities data. ROC statistics include: ROC, area under ROC curve (AUC), precision, accuracy.

Usage

calcRocStats(classes = NULL, probs = NULL, posClass = NULL, negClass = NULL)

Arguments

`classes`	A character vector of classifications.
`probs`	A numeric vector of probability values corresponding to the elements of `classes`.
`posClass`	Name of the positive class.
`negClass`	Name of the negative class.

Value

A list of ROC statistic objects and values.

Examples


library(TerrainWorksUtils)

# Generate test data with a bit of class probability overlap
classes <- c(rep("POS", 40), rep("NEG", 60))
probs <- c(runif(40, 0.4, 1.0), runif(60, 0.0, 0.6))

rocStats <- calcRocStats(classes, probs, "POS", "NEG")
