Factor Analysis Platform Options
The Factor Analysis platform red triangle menu enables you to select to view or hide the following report elements:
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.
Script
Lists the Script menu options for the platform. See the JMP Platforms chapter in the
Using JMP
book for details.

Initial Factor Analysis Report
