## 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.
