the wrapped prediction.

Constructor Detail

SortablePrediction

public SortablePrediction(weka.classifiers.evaluation.Prediction pred)

Initializes the container.

Parameters:

pred - the prediction to wrap

Method Detail

getPrediction

public weka.classifiers.evaluation.Prediction getPrediction()

Returns the stored prediction.

Returns:

the prediction

getAbsoluteDifference

public double getAbsoluteDifference()

Returns the absolute difference between actual and predicted value. Returns Double.MAX_VALUE if at least one of them is NaN.

Returns:

the absolute difference between actual and predicted or NaN

compareTo

public int compareTo(Object o)

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Uses the absolute difference between actual and predicted values.

Specified by:

compareTo in interface Comparable

Parameters:

o - the object to be compared.

Returns:

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Throws:

ClassCastException - if the specified object's type prevents it from being compared to this object.

toString

public String toString()

Returns a string representation of the wrapped prediction.

Overrides:

toString in class Object

Returns:

the string representation
