I am working on a sales forecast right now and I am not sure what type of model to use.
I have 17 Quarters of data(4 Full years + 1 QTR) and I am only looking to forecast 2 quarters into the future at maximum. My data is also very seasonal.
My only experience is using a simple multiple regression model, using the quarter number(to account for seasonality) and the time period as independent variables, which I worry wont be reactive enough to new data.
What model would be ideal for my scenario?
