WebbKey Results: Cumulative, Eigenvalue, Scree Plot. In these results, the first three principal components have eigenvalues greater than 1. These three components explain 84.1% of the variation in the data. The scree plot shows that the eigenvalues start to form a straight line after the third principal component. WebbThe first comparison that is useful is between Canonical Correlation Analysis and Principal Component Analysis (PCA). PCA is a method that finds linear combinations (called Principal Components) within a data set with the goal of maximizing the amount of variation that is explained by those Principal Components.
