public class Example2AttributePivoting
extends ExampleSetTransformationOperator

Transforms an example set by grouping multiple examples of single groups into single examples. The parameter group_attribute specifies an attribute which identifies examples belonging to the groups. The parameter index_attribute specifies an attribute whose values are used to identify the examples inside the groups. The values of this attributes are used to name the group attributes which are created during the pivoting. Typically the values of such an attribute capture subgroups or dates. If the source example set contains example weights, these weights may be aggregated in each group to maintain the weightings among groups.

Method Detail

apply

public IOObject[] apply()
                 throws OperatorException

Description copied from class: Operator

Implement this method in subclasses.

Specified by:

apply in class Operator

Throws:

OperatorException

getParameterTypes

public java.util.List<ParameterType> getParameterTypes()

Description copied from class: Operator

Returns a list of ParameterTypes describing the parameters of this operator. The default implementation returns an empty list if no input objects can be retained and special parameters for those input objects which can be prevented from being consumed.

Specified by:

getParameterTypes in interface ParameterHandler

Overrides:
