GLOSSARY ENTRY (DERIVED FROM QUESTION BELOW)

English term or phrase: weights
"The pooled proportion is calculated as a back-transformation of the weighted mean of the transformed proportions, using inverse arc sine variance weights for the fixed-effects model." Am citit referinte si trebuie sa recunosc ca statistica/matematica nu e un domeniu la indemana. Intreaga sintagma "arc sine variance weights" imi da batai de cap. Help?!!!

Multumesc anticipat!

ponderi
Explanation:
Media ponderata a n numere reale este egala cu suma produselor dintre ponderi si numere impartita la suma ponderilor.
Cand toate ponderile au aceeasi valoare, media ponderata este egala cu media aritmetica.

4.2.2. Varianţa (dispersia)
Dispersia este o măsură sintetică a împrăştierii (variaţiei) datelor într-o serie
statistică faţă de valoarea medie. Ea se calculează ca medie aritmetică simplă sau
ponderată a pătratelor abaterilor valorilor individuale de la tendinţa centrală (media
aritmetică x ) şi se notează de obicei cu litera alfabetului grec σ2.

Cu placere, dar cred ca mai corect este arcsinusul dispersiei ponderilor.

Asker: Multumesc pt raspuns :). De fapt, intrebarea era referitoare la ce anume se aplica aceasta pondere. SIntagma respectiva e cea care imi da batai de cap. Dar nu pot intreba decat strict referitor la un termen :).

Asker: Multumesc mult pt ajutor! Acum incep si eu sa ma luminez. Domeniul imi este complet strain :). Merci inca o data!
