Description

The Youden's Index evaluates the algorithm's ability to avoid failure.

Usage

YoudenIndex(resTable)

Arguments

resTable

the data.frame generated from the performanceNET (or one of the row of the matrix generated from the performanceIndex) function.

Value

The YoudenIndex function returns the value of the Youden's Index for a given predicted adjacency matrix.
