Pruned CHAID Tree Characterizing Non-SRD, December 2012. The pruned CHAID tree shows groups of subjects wherein rates of non-depression were greater than 87%. These nodes represent only a subset of all nodes generated by the CHAID tree. Of particular interest for this paper are nodes that are white (instead of blue); these nodes have been highlighted because they are partially defined by the presence of a media use quintile.
