The ACECLUS Procedure |

Unless the SHORT option is specified, the ACECLUS procedure displays the following items:

- Means and Standard Deviations of the input variables
- the
**S**matrix, labeled COV: Total Sample Covariances - the name or value of the matrix used for the Initial Within-Cluster Covariance Estimate
- the Threshold value if the PROPORTION= option is specified

For each iteration, PROC ACECLUS displays

- the Iteration number
- RMS Distance, the root mean square distance between all pairs of observations
- the Distance Cutoff (
*u*) for including pairs of observations in the estimate of the within-cluster covariances, which equals the RMS distance times the threshold - the number of Pairs Within Cutoff
- the Convergence Measure (
*e*_{i}) as specified by the METRIC= option

If the SHORT option is not specified, PROC ACECLUS also displays
the **A** matrix, labeled ACE: Approximate Covariance
Estimate Within Clusters.

The ACECLUS procedure displays a table of eigenvalues from the canonical analysis containing the following items:

- Eigenvalues of Inv(ACE)*(COV-ACE)
- the Difference between successive eigenvalues
- the Proportion of variance explained by each eigenvalue
- the Cumulative proportion of variance explained

If the SHORT option is not specified, PROC ACECLUS displays

- the Eigenvectors or raw canonical coefficients
- the standardized eigenvectors or standard canonical coefficients
