MAPOUTPUT subcommand (SPATIAL ASSOCIATION RULES command)
The MAPOUTPUT subcommand controls the display of interactive map output,
based on the specified criterion. To display results for multiple criteria, use multiple
MAPOUTPUT subcommands.
- DISPLAY=YES | NO
- Controls the display of the interactive map output. The default display setting is
YES. - NUMRULES=integer
- The maximum number of rules to include in the output.
- The value must be an integer between 2 and 10.
- The specified value is the maximum number of rules. The final number of rules included could be lower than that.
- The default value is 5.
- CRITERION=value
- The criterion to use for rules.
- Only one criterion can be specified on each subcommand.
- To display rules for more than one criterion, use multiple subcommands.
- CONFIDENCE
- The percentage of correct rule predictions. This is the default setting.
- RULESUPPORT
- The percentage of cases for which the rule is true. For example, if the rule is "If x=1 and y=2, then z=3," rule support is the actual percentage of cases in the data for which x=1, y=2, and z=3.
- LIFT
- Lift is a measure of how much the rule improves prediction compared to random chance. It is the ratio of correct predictions to the overall occurrence of the predicted value. The value must be greater than 1. For example, if the predicted value occurs 20% of the time and the confidence in the prediction is 80%, then the lift value is 4.
- CONDSUPPORT
- The percentage of cases for which the rule condition exists. For example, if the rule is "If x=1 and y=2, then z=3," condition support is the proportion of cases in the data for which x=1 and y=2.
- DEPLOYABILITY
- The percentage of incorrect predictions when the conditions are true. Deployability is equal to (1-confidence) multiplied by condition support or condition support minus rule support.
