Someone sent me some questions by email, and I decided to answer some of them here. How important is it that I know and understand the underlying mathematical framework to forecasting methods? I understand conceptually how most of them work, but I feel as if I may benefit from truly understanding the math.
The main benefit of understanding the mathematics behind different forecasting models is to be able to adapt the models when they don’t work well for your data.
