PERIOD Subcommand (SEASON command)

PERIOD indicates the size of the period.

• The specification on PERIOD indicates how many observations are in one period or season and can be any positive integer.
• If PERIOD is not specified, the periodicity that is established on TSET PERIOD is in effect. If TSET PERIOD is not specified, the periodicity that is established on the DATE command is used. If periodicity was not established anywhere, the SEASON command will not be executed.

Example

SEASON VARIABLES = SALES
  /PERIOD=12.

• In this example, a periodicity of 12 is specified for SALES.
