I'm searching for a software where I can import a large amount of data (5000 columns, unknown number of rows, about 20gb) and the software gives me a estimate correlation (does not have to be very accurate). Google translate says this is has to be the "correlation coefficient" (german "korrelationskoeffizient").
Use case: I work in a (rough translation) "waste heat power plant" as a student employee and want to optimize some processes. The 5000 columns are measurements taken from sensors. I want to know what value(s) will rise if I change another. Of course, in the end, this will be checked by people who understand this topic better than me.
The operating system does not matter. Preferred is windows or mac (workplace) but linux is ok, too (private).
