Big data is mainly not judged by causality and is mainly applicable to correlation analysis. Many correlation analyses do not require complex models and only require awareness of big data.

Big data is no longer the subject of computing and statistics, and the widespread use of business schools has shown that big data is officially coming into the wider application of the industry. "Most of the big data is irrelevant noise," says Natte Silver, a statisticians in the famous "Signal and noise" book. Unless there is good technical information to filter and deal with, otherwise will get into trouble. "Duke University's rich-card business school this fall began to recruit large data business analysis direction of the master's degree, the XI ' an Institute of Management will accept overseas large data analysis of doctoral students as the new admission of teaching staff ...
