Aleksey Nikolayev:
The most inexplicable (to me) paradox is that many people use anything but R for probabilistic and statistical calculations)

And what is so special about R that you can't find anywhere else?

This paradox is very easy to explain - they know what they are doing.

The biggest paradox for me is why the most advanced minds on this forum discuss anything but different TS :)

Almost no one writes in mql5 either

See, it just happened(!))))

Not really)

1) R is poorly represented in runet

2) it is not often studied in universities

Did SanSanych tell you that?

If they were talking about some specialised programmes instead of R, it would be understandable. Often just excel is used - even in higher education.
