A TYPE=ACE data set is created by the ACECLUS procedure, and it contains the approximate within-cluster covariance estimate, as well as eigenvalues and eigenvectors from a canonical analysis, among other statistics. It can be used as input to the ACECLUS procedure to initialize another execution of PROC ACECLUS. It can also be used to compute canonical variable scores with PROC SCORE and as input to PROC FACTOR, specifying METHOD=SCORE, to rotate the canonical variables. See Chapter 24: The ACECLUS Procedure, for details.
