Factor anaysis rotation

[Larry Lutsky]

SPSS gives me the percent of variance explained by the unrotated factors
when I do factor analysis.  I know rotation changes those percentages but
I don't see the the % variance explained after rotation.  This information
is more meaningful.  How can I get this from SPSS?

Larry,

Check the outline view in left pane... you should see an item "Total Variance Explained". This should show the "Initial Eigenvalues", the "Extraction Sums of Squared Loadings", and the "Rotation Sums of Squared Loadings" (what you are after). In a rotated solution this is standard output. HTH,
