Reading Centroid extracted factor matrix into SPSS for rotation, analysis

SOLUTION FOR ROTATION

First, make sure your centroid extraction matrix is set up properly. This means:

ROWTYPE_ as system variable with FACTOR as a string value for each row/case.

FACTOR_ as system variable with numeric values that labels each row/case.

Each factor in this matrix is one row/case. (I had mine transposed since that was how it was extracted...sigh...)

FACTOR MATRIX IN (FAC='path to centroid extraction matrix.sav')
/MISSING LISTWISE
/PRINT ROTATION 
/FORMAT BLANK(.544) 
/CRITERIA ITERATE(80) DELTA(0) 
/ROTATION OBLIMIN 
/METHOD=CORRELATION.

"I would like to use this centroid factor extraction data and create a new variable into Dataset A with the factor scores for each variable."

Perhaps you mean Factor Scores for Each case? That is NOT possible with simply the Factor Loadings. You need the case level data. Presumably you have that and want to acquire the corresponding factor scores. I would suggest you look into how these are calculated (see Algorithms) and write the necessary code using the MATRIX procedure. You won't get very far without it.
