Comments

A time variable is a variable, which values increase by one with each subsequent observation: 1, 2, 3, 4, and so on.

A dummy is a variable, each observation of which takes the values 0 or 1.

Dummy variables can be used in series and pointwise calculation modes. In pointwise mode, a dummy variable returns value at the current calculation point; in series mode it returns the ITimeSeries object containing values for the entire period.

Dummy variables can be used both in modeling method expressions, and in expressions IMsCompositeFormulaTerm.

Methods

	Method name	Brief description
	IsPeriod	The IsPeriod method returns dummy variable that determines whether the observation hits the specified period.
	NoDate	The NoDate method is used to mark start or end date of model sample period.
	SameDate	The SameDate method returns start period date for the IsPeriod dummy variable.
	Seas	The Seas method returns a dummy variable, each element of which determines whether the observation belongs to the specified period in the current year. The year is divided in accordance with series calendar frequency.
	Time	The Time method returns a time series, which value increases by 1 for each successive observation.
