Description

Calculate False Negative Rate (also called Miss Rate), defined as FN/P, for a given confusion matrix.

Usage

confusion.matrix.false.negative.rate(confusion.matrix)

confusion.matrix.miss.rate(confusion.matrix)

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

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

Arguments

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