D2MCS::MeasureFunction
-> PPV
new()
Method for initializing the object arguments during runtime.
PPV$new(performance.output = NULL)
performance.output
An optional ConfMatrix
parameter
to define the type of object used as basis to compute the PPV
measure.
compute()
The function computes the PPV achieved by the M.L. model.
PPV$compute(performance.output = NULL)
performance.output
An optional ConfMatrix
parameter
to define the type of object used as basis to compute the PPV
measure.
This function is automatically invoke by the ClassificationOutput object.
A numeric vector of size 1 or NULL if an error occurred.
