One who controls variables controls data. You tell with statistic not a word if you are a data scientist. I have been working both for data analytics and business strategy from the financial sector all the way to a mobile application startup with my expertise, statistical and data science i.e. machine learning and econometrics. I am also a business strategy expert with consulting experience. There is saying that "Practice without theory is mindless, Theory without Practice is pointless" I am vigorously learning up-to-date algorithms in machine learning and computing tools as well as my major field which is financial statistical analysis. ©
