Cluster Interpretation: Posterior Distributions
Background & Context
- On this page, we present Posterior Distributions 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:

Posterior Distributions for Cluster Interpretation
-
We bring up all of the networks' nodes by selecting Monitor Panel Context Menu > Sort > Target State Correlation.
-
In addition to displaying all Monitors, they are also automatically ordered in terms of their importance with the Target State C3.
-
The obvious starting point of our exploration is to set the evidence on the factor node that corresponds to our interest in C3, i.e., .
-
In addition to showing the posterior distributions of the nodes, BayesiaLab can display Absolute Variations: Monitor Context Menu > Absolute Variations. This highlights the difference in the distributions of C3 members versus the marginal distributions.
