Table 5 Discriminant function

From: Prediction of Class II improvement after rapid maxillary expansion in early mixed dentition

Predictive variables Unstandardized canonical discriminant function coefficients
Co-Gn 0.147
Ar^Go^N 0.221
Constant −26.399
  1. Individual Score = 0.147(Co-Gn) + 0.221(Ar^Go^N) − 26.399. Discriminant scores for group means (group centroids): successful group = −0.690; unsuccessful group = 1.034; and critical score = 0.667. Unstandardized discriminant function coefficients of the selected variable together with a calculated constant (−26.399) lead to the equation that provides individual scores for the assignment of a new case to GR or to BR
