|  | ## Loop Values

#### Synopsis

Iterates over the values of the specified attributes and applies the inner operators on the input example set while the current value can be accessed via a macro. In contrast to the ValueSubgroupIterator operator the inner operators are applied on the complete example set.

#### Description

In each iteration step, this meta operator executes its inner process to the input example set. This will happen for each possible attribute value of the specified attributes if `all` is selected for the `values` parameter. If `above p` is selected, an iteration is only performed for those values which exhibit an occurrence ratio of at least p. This may be helpful, if only large subgroups should be considered.

The current value of the loop can be accessed with the specified macro name.

#### Input

- example set: expects: ExampleSetMetaData: #examples: = 0; #attributes: 0

, expects: ExampleSet

#### Output

- out 1:

#### Parameters

- attribute: The nominal attribute for which the iteration should be defined
- iteration macro: Name of macro which is set in each iteration.
