  • Method for selecting node variables in a binary decision tree structure
    Patent number: 7809539
    Abstract: A method for selecting node variables in a binary decision tree structure is provided. The binary decision tree is formed by mapping node variables to known outcome variables. The method calculates a statistical measure of the significance of each input variable in an input data set and then selects an appropriate node variable on which to base the structure of the binary decision tree using an averaged statistical measure of the input variable and any co-linear input variables of the data set.
    Type: Grant
    Filed: December 6, 2002
    Date of Patent: October 5, 2010
    Assignee: SAS Institute Inc.
    Inventors: John C. Brocklebank, Bruce S. Weir, Wendy Czika
