how do lagged causal factors in the ‘Lag Decomposition Group’ decomposition group work?

Content

Hello

I saw some lagged causal factors are defined in 'Lag Decomposition Group' in some forecast profiles in Demand Management.

Is there any whitepaper with regard to how the causal factor data is populated?

Or 

Are those causal factors populated by engine to show coefficient lagged demand and forecast?

 

Thank You
