aThe ranking of the explanatory variables according to their importance in the model, in terms of strength of association, can be derived from the values of the importance weights: 0.00 to <0.50, no association; 0.50 to <0.75, weak association; 0.75 to <0.95, positive association; 0.95 to <0.99, strong association; 0.99 to ≤1.00, very strong association.
bImportance of the explanatory variables in the model.
cPart of the dependent variable variance explained by the explanatory variable: the sum of all partial R2 gives the Nagelkerke Pseudo-R2 (a statistic comparable to R2 in linear regressions).
