I'm being challenged to apply my academic skills to a project in the company where I work. I have to remodel and launch again in the market a product which we believe have potential, but that has having poor sells performance since it was launched. Additionally, I have a huge data base related to this product, available to me. These is demographic data about the clients who bought the product, the quantity and features of the product they use, many data about the channels where the product was bought and several information about when, where e how the product and its features are used. In total, I have at least 50 variables to analyze and the most part of them are time series. Since I don’t have any idea of which of them are relevant to explain the customer behavior or any other aspect of the phenomenon, what strategy do you recommend to use to get benefit of them?
