Association Rules - Output

Rules tables

Use these options to create one or more table types that display the best number of rules (based on a number you specify) for each selected criterion.

Confidence

Confidence is the ratio of rule support to condition support. Of the items with the listed condition values, the percentage that has the predicted consequent values. Creates a table that contains the best N association rules that are based on confidence to be included in the output (where N is the Rules to display value).

Rule Support

The proportion of items for which the entire rule, conditions, and predictions are true. For all items in the dataset, the percentage that is correctly accounted for and predicted by the rule. This measure gives an overall importance of the rule. Creates a table that contains the best N association rules that are based on rule support to be included in the output (where N is the Rules to display value).

Lift

The ratio of rule confidence and the prior probability of having the prediction. The ratio of the Confidence value for a rule versus the percentage the Consequent values occur in the overall population. This ratio gives a measure of how well the rule improves over chance. Creates a table that contains the best N association rules that are based on lift to be included in the output (where N is the Rules to display value).

Condition Support

The proportion of items for which the conditions are true. Creates a table that contains the best N association rules that are based on antecedent support to be included in the output (where N is the Rules to display value).

Deployability

A measure of what percentage of the training data satisfies the condition but not the prediction. This measure shows how often the rule misses. It is effectively the opposite of Confidence. Creates a table that contains the best N association rules that are based on deployability to be included in the output (N is the Rules to display value).

Rules to display

Set the maximum number of rules to display in the tables.

Model information tables

Use one or more of these options to select which model tables to include in the output.

• Field Transformations
• Records Summary
• Rule Statistics
• Most Frequent Values
• Most Frequent Fields

Sortable word cloud of rules.

Use these options to create a word cloud that displays the rules outputs. Words are displayed in increasing text sizes to indicate their importance.

Create a sortable word cloud.

Check this box to create a sortable word cloud in your output.

Default sort

Select the sort type to be used to when initially creating the word cloud. The word cloud is interactive and you can change the criterion in the Model Viewer to see different rules and sorts. You can choose from the following sort options:

• Confidence.
• Rule Support
• Lift
• Condition Support.
• Deployability

Max rules to display

Set the number of rules to be displayed in the word cloud; the maximum you can choose is 20.
