MODEL Subcommand (SEASON command)

MODEL specifies whether the seasonal decomposition model is multiplicative or additive.

• The specification on MODEL is the keyword MULTIPLICATIVE or ADDITIVE.
• If more than one keyword is specified, only the first keyword is used.
• MULTIPLICATIVE is the default if the MODEL subcommand is not specified or if MODEL is specified without any keywords.

Example

SEASON VARIABLES = VARX
  /MODEL=ADDITIVE.

• This example uses an additive model for the seasonal decomposition of VARX.
