Cluster Interpretation: Histograms

Background & Context

• On this page, we present the Histograms for cluster interpretation as an alternative to Most Relevant Explanations for Cluster Interpretation.
• To provide further context for Most Relevant Explanations for Cluster Interpretation, we compare several other approaches that can help interpret individual Clusters:
  • Setting Evidence for Cluster Interpretation: Posterior Distributions, Relationship with Target Node, Mosaic Analysis, Posterior Mean Analysis, Segment Profile Analysis, Histograms, Tornado Diagrams,
  • Optimization for Cluster Interpretation: Dynamic Profile, Target Optimization Tree
• More specifically, we compare all these approaches with regard to characterizing the state Cluster 3 of the Cluster Node  in the reference network.
• All analyses and instructions on this page refer to this reference network, which you can download here:

Histograms

• To launch Histograms, select Main Menu > Analysis > Visual > Target > Target's Posterior > Histograms.
• A new window opens up with one panel for each manifest node. At the top of the window we can select the Cluster of interest, which is Cluster 3 in our case.
  
• To explain the precise meaning of the panel content, we focus on the one for the node 10 - Knee Girth.
  
• The probability of an observation, i.e., an individual from the population, to belong to Cluster 3 is:
  • 9.23%, if 10 - Knee Girth ≤ 35.8
  • 17.32%, if 10 - Knee Girth ≤ 38.7
  • 7.27%, if 10 - Knee Girth >38.7
• The a priori probability of belonging to Cluster 3 is 12.96%, as indicated by the red line.
