angielski term

taking the nth root of the resulting product

angielski > polski Technika/inżynieria Matematyka i statystyka
A geometric mean return or the compound growth rate can be calculated by multiplying together one plus each return value, taking the nth root of the resulting product (where “n” represents the number of return values) and end by subtracting one.

1. Początek rozumiem tak:
Mam np. 12 rocznych zysków z kolejnych 12 lat.
Wykonuję 12 działań:
(Wartość zysku z pierwszego roku+1)
(Wartość zysku z drugiego roku+1)
....
Uzyskałem 12 wyników, które mnożę przez siebie.

Votes to reclassify question as PRO/non-PRO:

PRO (1): M.A.B.

When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.

How to tell the difference between "easy" and "pro" questions:

An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)

A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).

Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.

When deciding between easy and pro, err on the side of pro. Most questions will be pro.

* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

biorąc pierwiastek n-tego stopnia z wyniku mnożenia

Chodzi o średnią geometryczną. Po przemnożeniu tych 12 (n) wyników, bierzemy z tego pierwiastek 12 (n-tego) stopnia.
Na koniec odejmujemy 1, ale to już nie ze względu na średnią.
