Adjust Column and Rule Building Settings (Optional)

To adjust column and rule building settings

1. Click each column under Data Columns to view information about the analysis.

   

   In this example, sex is classified as Categorical data. This is because the database can contain only two values: male and female. Age is treated as a continuous variable (it can have values from 0 to around 100).

   Note: Rule Manager examines all the values in a data column. By default, if there are five or fewer distinct values, then the column is considered Categorical. This default can be adjusted; for example, if you frequently process a numeric code for Month (12 distinct values that should be treated as categories, not ranges). The default is set by the value of rulesFromData.distinctValuesLimit in the cpaa.properties file. This property file is typically located in the following directory:

   jboss\server\default\deploy\arm.ear\arm.war\WEB-INF\classes

   The Rule Manager lets you to set fixed categories or variable categories. This example shows that (by default) three age ranges have been automatically determined by the Rule Manager (by examining the statistics for the column - the mean and standard deviation).

2. Select Variable Categories, to create variable categories (for example, for age).
3. Select Fixed Categories, to create fixed categories.
4. Select Limit Rules by Importance, if you want to create restriction for the rule.

   If you select the Limit Rules by Importance checkbox, you can:

   • Enter the Number of Terms for the rule, if you selected the Limit Rules by Importance check box
   • Enter the Percent Accuracy for the rule, if you selected the Limit Rules by Importance check box.
   • Enter the Minimum Support needed for the rule, if you selected Limit Rules by Importance.
5. Click Next to map data columns to business terms.
