FIN and FOUT Subcommands (DISCRIMINANT command)

FIN specifies the minimum partial F value that a variable must have to enter the analysis. As additional variables are entered into the analysis, the partial F for variables already in the equation changes. FOUT specifies the smallest partial F that a variable can have and not be removed from the model.

• PIN and POUT take precedence over FIN and FOUT. That is, if all are specified, PIN and POUT values are used.
• If PIN and POUT are omitted, FIN and FOUT are used by default. If FOUT is specified but FIN is omitted, the default value for FIN is 3.84. If FIN is specified, the default value for FOUT is 2.71.
• You can set FIN and FOUT to any non-negative number. However, FOUT should be less than FIN if FIN is also specified.
• FIN and FOUT apply only to the stepwise methods and are ignored if the METHOD subcommand is omitted or if DIRECT is specified on METHOD.
