A bit of statisticsPrincipal Component Analysis (Karl Pierson 1901, Harold Hotelling 1930)
Multi-variance analysisEmphasises variance and patterns in dataData transformation for dimension reduction in analysis
Hierarchical clustering using Euclidian distanceForm clusters of “similar” respondents, starting with 1-member clusters“Similarity” (i.e., distance) calculated using Euclidian distance functionDistance between clusters uses “weighed pair-group centroid”
performs well with large variance in cluster sizes

A visual guide to PCA: What is significant?Scree plot of ”eigenvalues” of each of the 13 NIST characteristics
Kaiser-Guttman criterion:Characteristics with eigenvalues of 1.0 or greater are significant, and the residual can be discarded.

Our analysis vs. your needs
1. Is a full 13-characteristics analysis always required?2. Is the Kaiser-Guttman criterion always a good idea?3. How does the data projection influence the clustering?4. Does the chosen clustering distance threshold yield insights?5. Are there quality criteria for clusters?

Using the tool: What you can control1. Choose characteristics
for analysis.
2. Control significancethreshold.
3. Configure data projection
4. Control cluster size
5. Advanced clustering options coming soon
