APPLY Subcommand (SEASON command)

APPLY allows you to use a previously defined SEASON model without having to repeat the specifications.

• The only specification on APPLY is the name of a previous model in quotation marks. If a model name is not specified, the model that was specified on the previous SEASON command is used. Model names are either the default MOD_n names or the names that are assigned on the MODEL NAME command.
• To change one or more model specifications, specify the subcommands of only those portions that you want to change after the APPLY subcommand.
• If no series are specified on the command, the series that were originally specified with the model that is being reapplied are used.
• To change the series used with the model, enter new series names before or after the APPLY subcommand. If a series name is specified before APPLY, the slash before the subcommand is required.

Example

SEASON VARIABLES = X1
  /MODEL=ADDITIVE.
SEASON VARIABLES = Z1
  /APPLY.

• The first command specifies an additive model for the seasonal decomposition of X1.
• The second command applies the same type of model to series Z1.

Example

SEASON X1 Y1 Z1
  /MODEL=MULTIPLICATIVE.
SEASON APPLY
  /MODEL=ADDITIVE.

• The first command specifies a multiplicative model for the seasonal decomposition of X1, Y1, and Z1.
• The second command applies an additive model to the same three variables.
