The Cluster Summary report gives the following information:

Cluster

The cluster identifier.

Number of Members

The number of variables in the cluster.

Most Representative Variable

The cluster variable that has the largest squared correlation with its cluster component.

Cluster Proportion of Variance Explained

The clusterâ€™s proportion of variance explained by the first principal component among the variables in the cluster. If there is only one variable in the cluster, then this is 1. This statistic is based only on variables within the cluster rather than on all variables.

Total Proportion of Variation Explained

The overall proportion of variance explained by the cluster component. This is equivalent to using only the variables within each cluster to calculate the first principal component.

A note beneath the table gives the total proportion of variation explained by all the cluster components.
