Prior research using log-linear analysis to model church attendance (1=low; 2=medium; 3=high) as a function of age (young=0; old=1) and religion (non-Catholic=0; Catholic=1) found that the best fitting model {AR}{AC}{RC} had L2=7.25, df=2, indicating insufficient badness-of-fit (pp. 67-69). For these data exploratory novometric analysis predicting church attendance (ordered class variable) using religion (categorical attribute) and age (ordered attribute) identified a parsimonious, relatively weak model with stable classification training and LOO performance.
