PERIOD Subcommand (TSET command)

PERIOD indicates the size of the period to be used for seasonal differencing.

• The specification on PERIOD indicates how many observations are in one season or period and can be any positive integer.
• There is no default for the PERIOD subcommand.
• The specification on TSET PERIOD overrides the periodicity of DATE variables.
• If a period is specified within an individual procedure, it overrides the TSET PERIOD specification for that procedure.
