The Details report contains statistical information about the correspondence analysis and shows the values used in the plot.

Singular Value

Provides the singular value decomposition of the contingency table. For the formula, see Details Report in Correspondence Analysis.

Inertia

Lists the square of the singular values, reflecting the relative variation accounted for in the canonical dimensions.

Portion

Portion of inertia with respect to the total inertia.

Cumulative

Shows the cumulative portion of inertia. If the first two singular values capture the bulk of the inertia, then the 2-D correspondence analysis plot is sufficient to show the relationships in the table.

X variable c1, c2, c3

The values plotted on the Correspondence Analysis plot (Figure 7.11).

Y variable c1, c2, c3

The values plotted on the Correspondence Analysis plot (Figure 7.11).
