Proportion of variance plot. This graph is similar to the Scree Plot described above, but is used with a slightly different interpretation style.
Biplots are combinations of score plots and loading plots. Loading plot provide a means to visualize the coefficients for two selected principal components. Score plot provide a means of viewing the original data in the new (reduced) dimensional space of two indicated PCs (typically PC1 as the horizontal axis and PC2 as the vertical axis). Scree plot are used to visualize raw eigenvalues for each principal component (PC) identified in principal component analysis (PCA). Prism will automatically encode categorical text variables into numeric “dummy” variables.
