KEEP and DROP Subcommands (SAVE MODEL command)

KEEP and DROP allow you to save a subset of models. By default, all currently active models are saved.

  • KEEP specifies models to be saved in the model file.
  • DROP specifies models that are not saved in the model file.
  • Models can be specified by using individual model names or the names of the procedures that created them. To use procedure names, you must specify COMMAND on the TYPE subcommand.
  • Model names are either the default MOD_n names or the names that are assigned with MODEL NAME.
  • If you specify a procedure name on KEEP, all models that are created by that procedure are saved; on DROP, any models created by that procedure are not included in the model file.
  • Model names and procedure names cannot be mixed on a single SAVE MODEL command.
  • If more than one KEEP or DROP subcommand is specified, only the last subcommand is executed.
  • You can specify the keyword ALL on KEEP to save all models that are currently active. This setting is the default.

Example

SAVE MODEL OUTFILE='ACFCCF.DAT'
  /KEEP=ACF1 ACF2.
  • In this example, only models ACF1 and ACF2 are saved in model file ACFCCF.DAT.
