Figure 4.2 Principal Components on Correlations ReportĀ

The report gives the eigenvalues and a bar chart of the percent of the variation accounted for by each principal component. In this example, the first principal component accounts for almost 80% of the variation in the data. Together, the first two principal components account for almost all of the variation in the data (95.5%). There is a Score Plot and a Loadings Plot as well. See Principal Components Report.
