Frequently Asked Questions for CART
CART® is the ultimate classification tree that has revolutionized the entire field of advanced analytics and inaugurated the current era of data mining. CART, which is continually being improved, is the most important tool in modern data mining methods. Designed for both non-technical and technical users, CART can quickly reveal important data relationships that could remain hidden using other analytical tools.
CART is based on landmark mathematical theory introduced in 1984 by four world–renowned statisticians at Stanford University and the University of California at Berkeley. Salford Systems’ implementation of CART is the only decision tree software embodying the original proprietary code. The CART creators continue to collaborate with Salford Systems to enhance CART with proprietary advances.
CART is an acronym for Classification and Regression Trees, a decision-tree procedure introduced in 1984 by world-renowned UC Berkeley and Stanford statisticians, Leo Breiman, Jerome Friedman, Richard Olshen, and Charles Stone. Their landmark work created the modern field of sophisticated, mathematically- and theoretically-founded decision trees. The CART methodology solves a number of performance, accuracy, and operational problems that still plague many other current decision-tree methods. CART's innovations include:
- solving the “how big to grow the tree” problem;
- using strictly two-way (binary) splitting;
- incorporating automatic testing and tree validation; and
- providing a completely new method for handling missing values.
Salford Systems' CART is the only decision tree based on the original code of Breiman, Friedman, Olshen, and Stone. Because the code is proprietary, CART is the only true implementation of this classification-and-regression-tree methodology. In addition, the procedure has been substantially enhanced with new features and capabilities in exclusive collaboration with CART's creators. While some other decision-tree products claim to implement selected features of this technology, they are unable to reproduce genuine CART trees and lack key performance and accuracy components. Further, CART's creators continue to collaborate with Salford Systems to refine CART and to develop the next generation of data-mining tools.
