Country specific classification tree models.
<p>Note: Country specific classification tree models for the Czech Republic (top-left), Italy (top-right), Netherlands (bottom-left) and Sweden (bottom-right). The variables in the numbered boxes indicate the splitting variables identified in the recursive partitioning analysis. The cut-off value for each split, and the number of participants involved in each split is indicated next to the arrows diverting participants from the splitting variable. The six grey area's in the bottom of the lowest boxes (âterminal nodesâ), and the âpâ in these boxes indicates the proportion of participants in each partitioned area with scores of 7 or higher on the CAST. ânâ in the lowest boxes indicates the number of participants in each of the terminal nodes.</p
Ten models with optimal fit.
<p>Note: Variables correspond to those described in the section âBivariate analysisâ. AIC is Akaike Information Criterion, Nagelkerke R<sup>2</sup> provides a goodness-of-fit index between 0â1.</p><p>Ten models with optimal fit.</p
Performance statistics of the generic classification tree model.
<p>Note: Accuracy indicates the proportion of correctly classified cases, with associated confidence interval; No information rate (NIR) is 1-[proportion of CASTâ„7] in the sample; Difference between model accuracy and NIR tested using a one-sided binomial test; Sensitivityâ=â[number of correctly classified CAST â„7]/[number of CAST â„7 in sample]; Specificityâ=â[number of correctly classified CAST <7]/[number of CAST <7 in sample]; Positive predictive valueâ=â[number of correctly classified CAST â„7]/[all classified CAST â„7]; Negative predictive valueâ=â[number of correctly classified CAST <7]/[all classified CAST <7]. The country datasets contain both participants from the training and the validation dataset.</p><p>Performance statistics of the generic classification tree model.</p
