In the Multiple Correspondence Analysis platform, this option shows the Squared Cosines for the Column Points table or the Squared Cosines for the Row and Column Points. Also shows the Plot of Squared Cosines for the Column Points. This is a bar chart that shows, for each level of each Y variable, the squared cosine values for each of up to the first three dimensions shown.
X
Lists the columns specified as X, Factor variables.
Y
Lists the columns specified as Y, Response variables.
Category
Lists the levels of the X or Y variables.
Dimension 1, Dimension 2, Dimension 3
Lists the quality of the representation of the level by the indicated dimension. By default, the tables show results for up to the first three dimensions. Additional columns are hidden. To show these optional columns, right-click a table and select the dimension columns from the Columns submenu.
The values indicate the quality of each point for the indicated dimension. The squared cosine can be interpreted as the squared correlation of the point with the dimension. The sum of the squared cosines of the first two dimensions equalsQuality(dim=2) in the Summary Statistics report. See Statistical Details for Summary Statistics.
Note: If there are columns specified as X, Factor variables, the Squared Cosines report displays tables of both X and Y with the same report headings.
