evaluateAtTh: Model evaluation / accuracy assessment at one particular...

In benmack/oneClass: One-class classification in the absence of test data

Description

Calculation of accuracy for specified thresholds. This returns an object which, when printed, returns the confusion matrix and some model evaluation statistics.

Usage

evaluateAtTh(x, th, ...)

Arguments

x	an object of class ModelEvaluation,
th	the threshold
...	arguments passed to evaluate from the dismo package.

Value

an object of class ModelEvaluationAtTh which returns formated confusion matrix and accuracy statistics when printed.

Examples

# get an ModelEvaluation object
ev <- dismo::evaluate( p=rnorm(25, mean = 1), a=rnorm(100, mean = -1) )
# use evaluateAtTh in order to get an 
evAt0 <- evaluateAtTh(ev, th=0)
evAtMaxK <- evaluateAtTh(ev, th='max.kappa')
# print the confusion matrices and some model evaluation statistics 
evAt0
evAtMaxK
