VIN Subcommand (DISCRIMINANT command)

VIN specifies the minimum Rao’s V that a variable must have to enter the analysis. When you use METHOD=RAO, variables satisfying one of the other criteria for entering the equation may actually cause a decrease in Rao’s V for the equation. The default VIN prevents this but does not prevent the addition of variables that provide no additional separation between groups.

• You can specify any value for VIN. The default is 0.
• VIN should be used only when you have specified METHOD=RAO. Otherwise, it is ignored.
