INFLUENCE Subcommand (TREE command)

The INFLUENCE subcommand defines an optional influence variable that defines how much influence a case has on the tree-growing process. Cases with lower influence values have less influence, cases with higher values have more.

• The variable must be numeric.
• The dependent variable cannot be used as the influence variable.
• The weight variable (see the WEIGHT command) cannot be used as the influence variable.
• For QUEST, this subcommand is ignored and a warning is issued.
