Association Analysis Launch Window
Item
The categorical column that contains the item data to be analyzed.
ID
The column that identifies the transaction that an item belongs to.
By
Produces a separate report for each level of the By variable. If more than one By variable is assigned, a separate report is produced for each possible combination of the levels of the By variables.
Minimum Support
Specifies a minimum value for the proportion of occurrences of an item set. This value must be between 0 and 1. Only item sets with support equal to or exceeding this value are considered in the analysis.
Minimum Confidence
Specifies a minimum value for the proportion of occurrences that a consequent item set occurs within transactions that contain the conditional item set. This value must be between 0 and 1. Only association rules with confidence equal to or exceeding this value appear in the report.
Minimum Lift
Specifies a minimum dependency ratio. Lift values must be 0 or greater. Only association rules with lift equal to or exceeding this value appear in the report.
Maximum Antecedents
Specifies the maximum number of items in the condition item set. Association rules with more than this number of items in the condition set are not considered in the analysis.
Maximum Rule Size
Specifies the maximum number of items that appear in the union of the condition and consequent item sets. Association rules with more than this combined number of items are not considered in the analysis.
Note: You can use the minimum support, maximum antecedent, and maximum rule size options in the launch window to reduce computational time for large data sets. For more information about these measures, see Statistical Details for the Association Analysis Platform.
