First, let me state that I leaned statistics in German and hoped to find 
the right translation term.
For some terms, other languages may even not have a suitable translation.

Second, I would suggest to include the actual formulas in
such disputed docstrings.
I have seen that depending of the area of work, people tend use correct
scientific connotations or other terms (science vs. engineering).

The sphinxext of matplotlib offers a very convenient way to 
include maths formulas. These would make it clear.
In Excel (or Calc), the functions have different names but formulas remain.

Thanks for the explanations.

Kind regdards,
Timmie
