What do you need to study for deep data analysis?

Question

data mining

I'm interested in what you need to know (what areas of science) in order to get deductive patterns (not predictions) from the data. For example, I know Regression Analysis, what do I need to study to be a specialist in order to extract a large number of insights from data, maybe it's Statistics or Analytics or Math Analysis ....?
Thank you very much!

Start with Mathematical Analysis, since you have already learned such a word. The "fields of the sciences" should not disappear . And "to reveal a large number of insights from the data" - so you'd better go straight into intelligence. What to trifle. (By the way, explain to us ignoramuses what "data insights" are, please.)
