The file Sales.txt contains four columns holding weekly measures over a four year period of, respectively, the price of a product, the spending on advertising promotions, an indicator of the Christmas week and the sales of the product. The product is most likely a consumable for personal or home use, such as seen in the picture, but more precise detail is withheld for company confidentiality.For the same reason, all the series except the Christmas indicator are arbitrarily scaled.
