natural function

Natural Course Intervention

This function implements the natural course (i.e., model-based simulation) for the specified intervention variable in the data table newdf. Because newdf is initiated with the natural course, this function does nothing.

natural(newdf, pool, intvar, intvals, time_name, t)

Arguments

• newdf: Data table containing the simulated data at time $t$.
• pool: Data table containing the simulated data at times before $t$.
• intvar: Character string specifying the name of the variable to be intervened on in each round of the simulation.
• intvals: A list of user-specified values for the intervention.
• time_name: Character string specifying the name of the time variable in pool and newdf.
• t: Integer specifying the current time index.

Returns

No value is returned.
