Association Rules - Fields Options

On the Fields tab, you choose whether you want to use the field role settings that are already defined in upstream nodes, such as a previous Type node, or make the field assignments manually.

Use predefined roles

This option uses the role settings (such as targets, or predictors) from an upstream Type node (or the Types tab of an upstream source node). Fields with an input role are considered to be Conditions, fields with a target role are considered to be Predictions, and those fields that are used as inputs and targets are considered to have both roles.

Use custom field assignments

Choose this option if you want to assign targets, predictors, and other roles manually on this screen.

Fields

If you selected Use custom field assignments, use the arrow buttons to assign items manually from this list to the boxes on the right of the screen. The icons indicate the valid measurement levels for each field.

Both (Condition or Prediction)

Fields added to this list can take either the condition or prediction role in rules that are generated by the model. This is on a rule by rule basis, so a field might be a condition in one rule and a prediction in another.

Prediction only

Fields added to this list can appear only as a prediction (also known as a "consequent") of a rule. The presence of a field in this list does not mean that the field is used in any rules, only that if it is used it can be only a prediction.

Condition only

Fields added to this list can appear only as a condition (also known as an "antecedent) of a rule. The presence of a field in this list does not mean that the field is used in any rules, only that if it is used it can be only a condition.
