The arrival of the “big data” era is opening up new avenues in business, healthcare, etc. Much attention has been paid to scaling challenges arising from the huge increase in volume, velocity, and variety of data. Not as much attention has been paid to non-scaling-related issues that affect a number of fundamental assumptions in current statistical analysis approaches. Having more data is tremendously helpful in some analysis procedures. At the same time, having more data can also make the same analysis procedures fail in fundamental ways. We discuss some examples of these issues and how they might be fixed, as well as some examples where big data enhances analysis outcome.
