I obtained the access to Nielson retailer data around Jan. 2016. Boy! What a humongous data set! After looking at Nielson's data catalog, I decided to download only four data groups: fluid milk (module code: 3625), yogurt (module code: 3603), cheddar cheese (module code: 3550) and mozzarella (module code: 3546). Data were delivered through tsv (tab separated values) files. One for each product-year combo. All those files provide more than 5 million weekly price series. That's the starting point of this project.
