Category:Segmentation

There are three basic approaches to forming segments:

1. Judgment. For example, deciding to segment based on age. This is sometimes known as a priori segmentation. Within Displayr, judgment-based segmentations are usually created by first creating tables and visualizations to explore the data, and then creating new variables.
2. Cluster-based segmentation, which involves the use of techniques like latent class analysis, k-means cluster analysis, hierarchical cluster analysis and self-organizing maps to identify clusters of people that are broadly similar (see The Relationship Between Cluster Analysis, Latent Class Analysis and Self-Organizing Maps for an overview of the different algorithms). In Displayr, the options for creating segments include:
   • Latent class analysis, via Insert > Groups/Segments (Analysis).
   • K-Means cluster analysis, via Insert > More (Analysis) > Segments.
   • Many other options are available using R, via Insert > R Output (Analysis).
3. Predictive models, designed to identify segments of people (e.g., a CART may be used to identify the people most likely to switch telecommunications provider). These are available in Displayr via Insert > More (Analysis) > Classifier and Insert > Predictive Tree (Analysis).
