Classification tree analysis using TARGET

Tree models are valuable tools for predictive modeling and data mining. Traditional tree-growing methodologies such as CART are known to suffer from problems including greediness, instability, and bias in split rule selection. Alternative tree methods, including Bayesian CART (Chipman et al., 1998; Denison et al., 1998), random forests (Breiman, 2001a), bootstrap bumping (Tibshirani and Knight, 1999), QUEST (Loh and Shih, 1997), and CRUISE (Kim and Loh, 2001), have been proposed to resolve these issues from various aspects, but each has its own drawbacks. Gray and Fan (2003) described a genetic algorithm approach to constructing decision trees called tree analysis with randomly generated and evolved trees (TARGET) that performs a better search of the tree model space and largely resolves the problems with current tree modeling techniques. Utilizing the Bayesian information criterion (BIC), Fan and Gray (2005) developed a version of TARGET for regression tree analysis. In this article,...
