Confusion Matrix Measures - Bookmaker Informedness

Description

Calculate Bookmaker Informedness, defined as TPR+TNR-1, for a given confusion matrix.

Usage

confusion.matrix.bookmaker.informedness(confusion.matrix)

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

Arguments

confusion.matrix	Matrix - confusion matrix.
true.positive	Scalar - Cases identified as true positive
false.negative	Scalar - Cases identified as false negative
count.positive	Scalar - Total cases identified as positive - optional if first four parameters are used.
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 four parameters are used.
true.positive.rate	Scalar - True positive rate, overrides other parameters used to calculate TPR.
true.negative.rate	Scalar - True negative rate, overrides other parameters used to calculate TNR.

Value

A scalar with computed value.
