Kid,Am going to assume that you have a solid maths background but none re. analytics. I'd suggest doing that SAS programme, at Northwestern??? The quant/stats bitis not the problem, but when it comes to analytics and especially big data analytics, you need a good grasp of the tools, be it SAS or R.Places like SAS and SAP will offer you the opportunity to get your hands dirty. This is the best way to get into analytics.
