public static final double MISSING_VALUE

Constant representing a missing value. This should have the same value as weka.core.Instance.MISSING_VALUE

Method Detail

weight

public double weight()

Gets the weight assigned to this prediction. This is typically the weight of the test instance the prediction was made for.

Returns:

the weight assigned to this prediction.

actual

public double actual()

Gets the actual class value.

the actual class value, or MISSING_VALUE if no prediction was made.

predicted

public double predicted()

Gets the predicted class value.

Returns:
