FIG. 6.6 – Répulsions entre PPD <strong>et</strong> <strong>la</strong> proposition immédiate par charte<br />

2002, 82–84), en groupant ou en supprimant les lignes <strong>et</strong> les colonnes de manière à<br />

respecter les règles suivantes. 7 Comme le présente A<strong>la</strong>n Agresti (2002, 84):<br />

«1. The df 8 for the subtables must sum to df for the full table.<br />

Each cell count in the full table must be a cell count in one and only one subtable.<br />

2. Each marginal total of the full table must be a marginal total for one and only one subtable.»<br />

7<br />

Ces règles de décomposition sont basées sur le rapport de vraisemb<strong>la</strong>nce, statistique proche<br />

duχ 2 noté G2 , dont <strong>la</strong> formule (cf. Howell 1998, 179) est (o <strong>et</strong> e ont <strong>la</strong> même signification<br />

que <strong>dans</strong> <strong>la</strong> formule duχ 2 (voir note 14, p. 178):<br />

G 2 <br />

o<br />

<br />

= 2 o×ln<br />

(6.1)<br />

e<br />

Le rapport de vraisemb<strong>la</strong>nce calculé sur <strong>la</strong> table initiale correspond à <strong>la</strong> somme des rapports<br />

de vraisemb<strong>la</strong>nce de toutes les sous-tables obéissant aux critères cités.<br />

8 C’est-à-dire le nombre de degrés de liberté.<br />
