Rotated Component Matrix in Proc FACTOR

[niam]

Hi,

How can I create a  Rotated Component Matrix in Factor analysis or Principle component analysis.

SPSS creates this automatically and makes it much easier to interpret the data by grouping the related variables together under a component/factor. I could not figure out how the same table can be created in SAS.

On the last page of the document in this link you can see an example of the matrix created with SPSS

Thanks for your help in advance

Hi,

Just add rotate=v (for varimax rotation) in proc factor syntax. Something like this

proc factor data=have rotate=v;

var a b c d;

run;

Thanks!
