The Multiple Factor Analysis red triangle menu includes the following options.
Block Weights
Shows or hides the first eigenvalue for each block as well as the weight of that eigenvalue. The weight is the inverse of the square root of the first eigenvalue.
Eigenvalues
Shows or hides a table of eigenvalues that correspond to the consensus dimensions, in order, from largest to smallest.
Eigenvectors
Shows or hides a table of the eigenvectors for each of the consensus dimensions, in order, from left to right. Using these coefficients to form a linear combination of the original variables produces the consensus principal component variables.
Variable Loadings
Shows or hides the loadings for each column. As in principal components analysis, loadings represent correlations of variables with components. Values near zero indicate the variable has little effect on the consensus dimension.
Variable Partial Contributions
Shows or hides a table that contains the partial contributions of variables. The partial contributions represent the percentage of variance that each variable contributes to the consensus dimension.
Variable Squared Cosines
Shows or hides a table that contains the squared cosines of variables. The sum of the squared cosine values across consensus dimensions is equal to 1 (100%) for each variable. The squared cosines represent the overlap in variance between variables and dimensions.
Tip: For the variable loadings, variable partial contributions, and variable squared cosines, values near zero indicate the variable is weakly related to the consensus dimension. Values far from zero indicate a strong association. The degree of transparency for the table values highlights these effects.
Summary Plots
Shows or hides the summary plots. The summary plots include the plot of the eigenvalues or score plot and the loading plot.
Consensus Map
Shows or hides the consensus map. See Consensus Map.
Biplot
Shows or hides a plot that is an overlay of the score and loadings plots. Use the controls to select any two dimensions for the plot.
Partial Axes Plot
Shows or hides a partial axes plot. This plot displays correlations between PCA scores from separate block analyses and the consensus principal component. Use the controls to select any two dimensions for the plot. Click a block in the legend to highlight that block in the plot.
Display Options
Arrow Lines
Enables you to show or hide arrows on the loading plot, and the partial axes plot. Arrows are shown if the number of variables is 1000 or fewer. If there are more than 1000 variables, the arrows are off by default.
Show Labels
Shows or hides block name labels on all points in the consensus map and bi-plot. Shows or hides column name labels on all points in the partial axes plot.
Tip: Use row labels to identify centroids on the consensus map and data points on the loading plot.
Block Partial Contributions
Shows or hides the sum of the variable contributions within the block.
Block Partial Inertias
Shows or hides the block contribution multiplied by the eigenvalue for the principal component and then divided by 100.
Block Squared Cosines
Shows or hides the block inertia squared and divided by the sum of squares used to calculate the eigenvalues. The values have a range between 0 and 1. The Block Squared Cosines can be considered as the percentage of the block variance explained by each principal component.
Block Partial and Consensus Correlations
Shows or hides a matrix of correlation coefficients between block partial scores and consensus principal component scores. The matrix is rectangular because only correlations between concordant dimensions are displayed.
RV Correlations
Shows or hides a matrix of squared correlation coefficients between blocks.
Lg Coefficients
Shows or hides a matrix of similarity measures between blocks.
Save Individual Scores
Saves the item consensus principal components to new columns in the data table. If one or more categorical supplementary variables are used, this option also saves individual scores for each level of the supplementary variables to a new data table.
Save Individual Squared Cosines
Saves the item squared cosines to new columns in the data table. If one or more categorical supplementary variables are used, this option also saves categorical supplementary variable squared cosines to a new data table.
Save Individual Partial Contributions
Saves the item partial contributions to new columns in the data table. If one or more categorical supplementary variables are used, this option also saves categorical supplementary partial contributions to a new data table.
Save Block Partial Scores
Saves the block partial scores to a new data table.
Save Partial Axes Coordinates
Saves the partial axes coordinates to a new data table.
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.
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.
