Hello.
I got a database with the evolution of my sales across time. Each row represents a product and the columns represents equal gaps of time. The value of each cell is the amount sold. From that you can draw curves for each product.
Now I have a new product, or a new curve, and I want to know which of the existing curves matches the best with the new one.
Which is the best way to do that?
Thanks for the attention.
