At my job, I have years of customer, sales, and demographic data. I'd like to explore options for mining and visualizing this data. Who buys X product but not Y product? Are our products in discrete groups that tend to be purchased together but with little overlap? Does AB marketing message work in one county, while XY marketing message works better in another?
I want to become an expert in answering these kinds of questions. What software should I use for this? What software does, say, Nate Silver use for his computations? I'm willing to invest time and money to learn, but I don't know where to start.
