Cax ou Cay Précision de capacité des valeurs x ou y

,

Cpx ou Cpy Précision de la capacité potentielle des valeurs x et y ,

,

Cpkx ou Cpky Minimum (CPU, CPL) des valeurs x ou y, où CPU est la limite spéc. supérieure de la précision de capacité et CPL est la limite spéc. inférieure de la précision de capacité

Cpkx = Min (C PUX , C PLX) = C px(1 – C ax ) C pky = Min (C PUY , C PLY) = C py(1 – C ay )

(Note) : En calculant la capacité de traitement dans le mode 2–VAR, x n et y n sont indépendantes les unes des autres.

„Distribution de probabilité

Etapes : ( Voir l’Exemple 55. )

1. Selon les bases de données dans le mode 1–VAR, pressez [ DATA ] et trois menus apparaissent : DATA–INPUT, LIMIT–SET, DISTR. Veuillez choisir DISTR et pressez

[ ].

2.Entrez une valeur a x , puis pressez [ ].

3.Pressez [ STATVAR ] et faîtes défiler le menu des résultats

statistiques avec [

] ou [ ] pour trouver les variables de la

distribution de probabilité. (Voir Tableau ci-dessous)

Variable

Sens

tValeur de test

P ( t ) Représente la fraction cumulative de la distribution normale inférieure à la valeur t

R ( t ) Représente la fraction cumulative de la distribution normale incluse entre la valeur t et 0. R ( t ) =1 – ( t )

Q ( t ) Représente la fraction cumulative de la distribution normale supérieure à la valeur t.

Q ( t ) = 0.5 – ( t )

„Régression linéaire

Etapes : ( Voir l’Exemple 56. )

1.Selon les bases de données dans le mode 2–VAR , pressez [ STATVAR] et faîtes défiler le menu des résultats statistiques

avec [ ] ou [3] pour trouver a, b, ou r.

2.Pour prédire une valeur pour x ( ou y ) donné une valeur de y

( ou x ), sélectionnez la variable x ' ( ou y ' ), pressez [ ],
