Situation is that we have branches in every city, selling food.
I feed the time series algorithm with the actual date, as the key time, and total sales of that day, as the input and predict. Predictions are not bad. But,
I would like to know if i can improve the predictions by for example feeding with the number of branches(a new branch can increase the sales number of course) or the number of food types?
And If i can, how? If i can't, is there a better approach/algorithm?
