The MCA red triangle menu contains options that enable you to customize reports according to your needs.
Cross Table
Shows or hides a Burt or contingency table as appropriate for variable roles selected. See Cross Table.
Correspondence Analysis
Shows a submenu of correspondence analysis reports. The reports available are determined by the type of analysis that you conduct. These reports give the plots, details, coordinates, and summary statistics.
Show Plot
Shows or hides the two-dimensional cloud of categories in the plane described by the first two principal axes. This plot appears by default. The plot uses isometric scaling. See Show Plot.
Show Detail
Show or hides the details of the analysis including the singular values, inertias, ChiSquare statistics, percent, and cumulative percent. This report appears by default. See Show Detail.
Show Adjusted Inertia
Shows or hides reports of the Benzecri and Greenacre adjusted inertia. See Benzécri (1979) and Greenacre (1984). This option is not available when there are one or more X variables. See Show Adjusted Inertia.
Show Coordinates
Shows or hides a report of up to the first three principal coordinates for the categories in the analysis, as appropriate. See Show Coordinates.
Show Summary Statistics
Shows or hides a report of the summary statistics, Quality, Mass, and Inertia, for each category in the analysis. See Show Summary Statistics.
Show Partial Contributions to Inertia
Shows or hides a report of the contribution of each category to the inertia for each of up to the first three dimensions. See Show Partial Contributions to Inertia.
Show Squared Cosines
Shows or hides a report of the squared cosines of each category for each of up to the first three dimensions. The report includes 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. See Show Squared Cosines.
Cochran’s Q Test
(Available only when all of the Y variables have the same set of only two levels and the X variable has a unique value for each row.) Provides Cochran’s Q statistic, which tests that the marginal probability of a specific response is unchanged across the Y variables. Cochran’s Q statistic is a generalization of McNemar’s statistic for more than two response variables. See Agresti (2013). See Cochran’s Q Test.
3D Correspondence Analysis
Shows or hides the three-dimensional cloud of categories of the Y, X, and Z variables in the space described by the first three principal axes. This option is not available if there are less than three dimensions.
Save Coordinates
Saves the principal coordinates to one or more JMP data tables. Column coordinates, row coordinates, supplementary column coordinates, and supplementary row coordinates are saved to separate JMP data tables. You can choose how many columns to save.
Save Coordinate Formula
Saves formula columns to the data table for the principal coordinates in multiple dimensions. The value for each observation is the average of the coordinates for the Y variables scaled by the singular value for each dimension. You can choose how many columns to save.
Cross Table of Supplementary Rows
(Available when one or more supplementary Z and X variables are specified or when an ID is specified.) Shows or hides a Burt or contingency table, dependent on the following rules:
– When one or more X and Z variables are specified, shows or hides a contingency table of the X variable(s) versus the response variable(s).
– When an ID and no X variables are specified, shows or hides a Burt table for the supplementary observations. The supplementary observations are those observations for which the ID variable is equal to 0.
– When an ID and one or more X variables are specified, shows or hides a contingency table for the supplementary observations. The supplementary observations are those observations for which the ID variable is equal to 0.
Cross Table of Supplementary Columns
(Available when one or more supplementary Z variables are specified.) Shows or hides a contingency table dependent on the following rules:
– When no X variable is specified, shows or hides a contingency table of the Response variable(s) versus the supplementary variable(s).
– When one or more X variables are specified, shows or hides a contingency table of the X variable(s) versus the supplementary variable(s).
Mosaic Plot
(Available only when there is one X variable and one Y variable.) Shows or hides a mosaic plot Y versus X. A mosaic plot is a stacked bar chart where each segment is proportional to its group’s frequency count.
Tests for Independence
(Available only when there is one X variable and one Y variable.) Shows or hides the tests for independence between the X and Y variables. There are two versions of this test, the Pearson form and the Likelihood Ratio form, both with chi‐square statistics.
See “Local Data Filters in JMP Reports”, “Redo Menus in JMP Reports”, “Group Platform”, and “Save Script Menus in JMP Reports” in Using JMP for more information about the following options:
Local Data Filter
Shows or hides the local data filter that enables you to filter the data used in a specific report.
Redo
Contains options that enable you to repeat or relaunch the analysis. In platforms that support the feature, the Automatic Recalc option immediately reflects the changes that you make to the data table in the corresponding report window.
Platform Preferences
Contains options that enable you to view the current platform preferences or update the platform preferences to match the settings in the current JMP report.
Save Script
Contains options that enable you to save a script that reproduces the report to several destinations.
Save By-Group Script
Contains options that enable you to save a script that reproduces the platform report for all levels of a By variable to several destinations. Available only when a By variable is specified in the launch window.
Note: Additional options for this platform are available through scripting. Open the Scripting Index under the Help menu. In the Scripting Index, you can also find examples for scripting the options that are described in this section.
