In the Multiple Correspondence Analysis platform, this option shows the Partial Contributions to Inertia for the Column Points table or the Partial Contributions to Inertia for the Row and Column Points tables. Also shows the Plot of Partial Contributions to Inertia for the Column Points. This is a bar chart that shows, for each level of each Y variable, its partial contributions to each of the dimensions shown in the table.
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 contribution of the response or factor level to the inertia of the indicated dimension. By default, the tables show columns 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.
Each level of each response contributes to the inertia of each dimension. The partial contributions within each dimension sum to 1.
The contribution of a row or column to the inertia of a dimension is calculated as follows:
contribution = (mass)(coordinate)2/(dimension inertia)
Note: If there are columns specified as X, Factor variables, the Partial Contributions to Inertia report displays tables of both X and Y with the same report headings.
