Constructor Detail

GeneralRegression

public GeneralRegression(org.w3c.dom.Element model,
                         Instances dataDictionary,
                         MiningSchema miningSchema)
                  throws java.lang.Exception

Constructs a GeneralRegression classifier.

Parameters:

model - the Element that holds the model definition

dataDictionary - the data dictionary as a set of Instances

miningSchema - the mining schema

Throws:

java.lang.Exception - if there is a problem constructing the general regression object from the PMML.

Method Detail

toString

public java.lang.String toString()

Return a textual description of this general regression.

Overrides:

toString in class java.lang.Object

Returns:

a description of this general regression

distributionForInstance

public double[] distributionForInstance(Instance inst)
                                 throws java.lang.Exception

Classifies the given test instance. The instance has to belong to a dataset when it's being classified.

Overrides:

distributionForInstance in class Classifier

Parameters:

inst - the instance to be classified

Returns:

the predicted most likely class for the instance or Instance.missingValue() if no prediction is made

Throws:

java.lang.Exception - if an error occurred during the prediction

getRevision

public java.lang.String getRevision()

Description copied from class: Classifier

Returns the revision string.

Specified by:

getRevision in interface RevisionHandler

Overrides:

getRevision in class Classifier

Returns:

the revision
