Simultaneous Factor Analysis for Several Groups
ERight-click the arrow that points from spatial to cubes and choose Object Properties
from the pop-up menu.
EIn the Object Properties dialog box, click the Parameters tab.
EType cube_s in the Regression weight text box.
ESelect All groups. A check mark appears next to it. The effect of the check mark is to
assign the same name to this regression weight in both groups.
ELeaving the Object Properties dialog box open, click each of the remaining single-
headed arrows in turn, each time typing a name in the Regression weight text box.
Keep this up until you have named every regression weight. Always make sure to
select (put a check mark next to) All groups. (Any regression weights that are already
fixed at 1 should be left alone.)
