About this course

Course code TPCLUS94
Duration 2 Days

The course looks at the theoretical and practical implications of a wide array of clustering techniques currently available in SAS. The techniques considered include cluster pre-processing, variable clustering, k-means clustering, and hierarchical clustering

Prerequisites

Before attending this course, you should

  • be able to execute SAS programs and create SAS data sets. You can gain this experience by completing the SAS Programming 1: Essentials course.
  • have completed a graduate-level course in statistics or the Introduction to Statistics Using SAS 9.2: ANOVA, Linear Regression and Logistic Regression course.
  • have an understanding of matrix algebra.

Who should attend

Intermediate or senior level statisticians, data analysts, and data miners

Delegates will learn how to

  • prepare and explore data for a cluster analysis
  • distinguish among many different clustering techniques, making informed choices about which to use
  • evaluate the results of a cluster analysis
  • determine the appropriate number of clusters to retain
  • profile and describe clustered observations
  • score observations into clusters.
