Criteria
for the Rotation
qBasically, the criteria of rotating
EOFs is to measure the “simplicity” of the EOF structure.
qBasically, simplicity of structure is supposed to occur when most of the elements of the
eigenvector are either of order one (absolute value) or zero, but not in between.
qThere are two popular rotation criteria:
(1) Quartimax Rotation
(2) Varimax Rotation
