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,
