\title{Calculate receiver operator measures.}
\usage{
calculateROCMeasures(pred)
\method{print}{ROCMeasures}(x, abbreviations = TRUE, digits = 2, ...)
}
\arguments{
\item{pred}{(\link{Prediction})\cr
Prediction object.}
\item{x}{(\code{ROCMeasures})\cr
Created by \link{calculateROCMeasures}.}
\item{abbreviations}{(\code{logical(1)})\cr
If \code{TRUE} a short paragraph with explanations of the used measures is printed additionally.}
\item{digits}{(\code{integer(1)})\cr
Number of digits the measures are rounded to.}
\item{...}{\code{(any)}\cr
Currently not used.}
}
\value{
(\code{ROCMeasures}).
A list containing two elements \code{confusion.matrix} which is
the 2 times 2 confusion matrix of absolute frequencies and \code{measures}, a list of the above mentioned measures.
}
\description{
Calculate the absolute number of correct/incorrect classifications and the following evaluation measures:
\itemize{
\item \code{tpr} True positive rate (Sensitivity, Recall)
\item \code{fpr} False positive rate (Fall-out)
\item \code{fnr} False negative rate (Miss rate)
\item \code{tnr} True negative rate (Specificity)
\item \code{ppv} Positive predictive value (Precision)
\item \code{for} False omission rate
\item \code{lrp} Positive likelihood ratio (LR+)
\item \code{fdr} False discovery rate
\item \code{npv} Negative predictive value
\item \code{acc} Accuracy
\item \code{lrm} Negative likelihood ratio (LR-)
\item \code{dor} Diagnostic odds ratio
}
For details on the used measures see \link{measures} and also
\url{https://en.wikipedia.org/wiki/Receiver_operating_characteristic}.
The element for the false omission rate in the resulting object is not called \code{for} but
\code{fomr} since \code{for} should never be used as a variable name in an object.
