In burrm/lolcat: Miscellaneous Useful Functions

Confusion Matrix Measures - False Positive/Fallout Rate

Description

Calculate False Positive Rate (sometimes called Fallout rate), defined as FP/N, for a given confusion matrix.

Usage

confusion.matrix.false.positive.rate(confusion.matrix)

confusion.matrix.fall.out(confusion.matrix)

confusion.matrix.false.positive.rate.simple(
  false.positive = 0,
  true.negative = 1,
  count.negative = false.positive + true.negative
)

confusion.matrix.fall.out.simple(
  false.positive = 0,
  true.negative = 1,
  count.negative = false.positive + true.negative
)

Arguments

confusion.matrix	Matrix - confusion matrix.
false.positive	Scalar - Cases identified as false positive
true.negative	Scalar - Cases identified as true negative
count.negative	Scalar - Total cases identified as negative - optional if first two parameters are used.

Value

A scalar with computed value.
