uRégression quadratique
La formule de régression pour la régression quadratique
est :
y = A + Bx + Cx
2
.
Exemple:
Effectuez une régression quadratique
pour déterminer les termes de la
formule de régression pour les
données ci-contre. Utilisez ensuite la
formule de régression pour estimer les
valeurs pour
n (valeur estimée de y)
pour
xi = 16 et m (valeur estimée de x)
pour
yi = 20.
Dans le mode REG:

Précautions concernant la saisie de données
S S saisit deux fois la même donnée.
•Vous pouvez aussi saisir plusieurs fois les mêmes
données en utilisant
A G. Par exemple, pour saisir
cinq fois “20 et 30”, il faut appuyer sur 20
P 30 A G
5 S.
•Vous obtiendrez les mêmes résultats quel que soit l’ordre
dans lequel vous appuyez sur les touches.
Les précautions à prendre lors de l’édition de données
pour l’écart-type sont aussi valides pour les calculs de
régression.
