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.

|
SameDate |
The SameDate method returns period start date for dummy variable. |
