Decision Tree Modeling

Course Details
Code: DMDT42
Tuition (USD): $1,600.00 • Classroom (2 days)
$1,600.00 • Virtual (2 days)

This course includes discussions of tree-structured predictive models and the methodology for growing, pruning, and assessing decision trees. In addition, this course examines many of the auxiliary uses of trees such as exploratory data analysis, dimension reduction, and missing value imputation.

Skills Gained

  • build tree-structured models, including classification trees and regression trees
  • use the methodology for growing, pruning, and assessing decision trees
  • use decision trees for exploratory data analysis, dimension reduction, and missing value imputation.

Who Can Benefit

  • Predictive modelers and data analysts who want to build decision trees using SAS Enterprise Miner software

Prerequisites

  • Before attending this course, you should
  • have an understanding of basic statistical concepts. You can gain this knowledge from the Statistics I: Introduction to ANOVA, Regression, and Logistic Regression course.
