Modifier and Type	Method	Description
java.lang.Double	calculateAvgMeasure(java.util.List<double[]> actual, java.util.List<double[]> expected)	Computes the measure for lists of input actual and the expected outcome expected and aggregates the measured values with the mean, as this is the most frequently used aggregate function.
java.lang.Double	calculateMeasure(double[] actual, double[] expected)	Computes the measure for a measured input actual and the expected outcome expected.

calculateMeasure

public java.lang.Double calculateMeasure(double[] actual,
                                         double[] expected)

Description copied from interface: IMeasure

Computes the measure for a measured input actual and the expected outcome expected.

Parameters:

actual - The actually available values.

expected - The expected values to compare the actual values with.

Returns:

The return value of the measure.

calculateAvgMeasure

public java.lang.Double calculateAvgMeasure(java.util.List<double[]> actual,
                                            java.util.List<double[]> expected)

Description copied from interface: IMeasure

Computes the measure for lists of input actual and the expected outcome expected and aggregates the measured values with the mean, as this is the most frequently used aggregate function.

Specified by:

calculateAvgMeasure in interface IMeasure<double[],java.lang.Double>

Overrides:

calculateAvgMeasure in class ADecomposableDoubleMeasure<double[]>

Parameters:

actual - The list of actually available values.

expected - The list of expected values to compare the actual values with.

Returns:

The mean of return values as output by the instance-wise measure.
