Categorical Principal Components Analysis Loading Plots

The Loading Plots dialog box controls the variables that are included in the plot, display of centroids in the loadings plot, and display of plots of variance accounted for.

Variance accounted for. For each dimension, displays a plot of variance accounted for.

Display component loadings. If selected, a plot of the component loadings is displayed.

Loading Variables. You can choose to use all variables for the component loadings plot or select a subset.

Include centroids. Variables with multiple nominal scaling levels do not have component loadings, but you can choose to include the centroids of those variables in the plot. You can choose to use all multiple nominal variables or select a subset.
