Troubleshooting
Problem
In the SPSS Classification Tree dialog, I see a box for "Influence variable". Please define the influence variable and its role in the Tree growing methods. The "Syntax Reference Guide" states that 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." This seems like a weight variable, but placing my weight variable in the Influence variable box has no apparent effect on the counts and percentages in the tree node statistics.
