Constructor Detail

### Regression

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

  Constructs a new PMML Regression.

  Parameters:
    `model` - the `Element` containing the regression model
    `dataDictionary` - the data dictionary as an Instances object
    `miningSchema` - the mining schema
  Throws:
    `java.lang.Exception` - if there is a problem constructing this Regression

Method Detail

### toString

    public java.lang.String toString()

  Return a textual description of this Regression model.

  Overrides:
    `toString` in class `java.lang.Object`

### 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
