Factor Analysis Platform Options
The following options are accessed by clicking the Factor Analysis red triangle menu in the report window:
Eigenvalues
A table that indicates the total number of factors extracted based on the eigenvalues (that is, the amount of variance contributed by each factor). The table includes the percent of the total variance contributed by that factor, a bar chart illustrating the percent contribution, and the cumulative percent contributed by each successive factor. The number of eigenvalues greater than or equal to 1.0 can be taken as the number of sufficient factors for analysis.
Scree Plot
A plot of the eigenvalues versus the number of components (or factors). The plot can be used to determine the number of factors that contribute to the maximum amount of variance. The point at which the plotted line levels out can be taken as the number of sufficient factors for analysis. See Initial Factor Analysis Report for an example of scree plots.
See Local Data Filter, Redo Menus, and Save Script Menusin the Using JMP book 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.
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.
