Decision Tree: CART

What is CART? Classification And Regression Trees Developed by Breiman, Friedman, Olshen, Stone in early 80’s Introduced tree-based modeling into the statistical mainstream Rigorous approach involving cross-validation to select the optimal tree One of many tree-based modeling techniques CART -- the classic CHAID C5 0

Classification and regression trees

7 Prune the tree with the CART method CHAID15 employs yet another strategy If X is an ordered variable, its data values in the node are split into 10 intervals and one child node is assigned to each interval If X is unordered, one child node is assigned to each value of X Then, CHAID uses significance tests and Bonferroni corrections to

COMPARISON OF DIFFERENT DATA MINING ALGORITHMS FOR PREDICTION

step is more exhaustive than CHAID, by continuing to merge categories of the predictor variable until only two super categories are left The Exhaustive CHAID can find the best split for each predictor variable (Biggs et al , 1991) For regression and classification problems, the tree-based CART, CHAID, and Exhaustive CHAID data

Evaluation of CART, CHAID, and QUEST Algorithms: A Case Study

Decision Tree-based Parametric Analysis of a CNC Turning Process

classification and regression tree (CART) and Chi-squared automatic interaction detection (CHAID) are employed here to investigate the effects of the considered CNC turning parameters on the responses The relative performance of both the algorithms is also compared with respect to solution accuracy and prediction risk

[PDF] A Basic Introduction to CHAID - SmartDrill

A Basic Introduction to CHAID CHAID, or Chi-square Automatic Interaction Detection, is a Classification Tree technique that not only evaluates complex interactions among predictors, but also displays the modeling results in an easy-to-interpret tree diagram The "trunk" of the tree represents the total modeling database CHAID then creates a first layer of "branches" by displaying values of the

[PDF] CHAID and Earlier Supervised Tree Methods

CHAID (Chi-square Automatic Interaction Detector), introduced by Kass (1980) as an evolution of AID and THAID, is certainly nowadays the most popular among these earlier statistical supervised tree growing techniques We describe its functioning in details hereafter 2 CHAID As indicated by its name, CHAID uses a Chi-square splitting criterion More
