Parameters | Predictive Modeling | Correlation Radius for Clustering

Correlation Radius for Clustering
Use this option to specify a correlation value to be used to determine the minimum radius for clustering . This value must be between 0 and 1. The higher the correlation, the more clusters that are defined with members of each cluster being more highly correlated with one another than with other clusters. A value of 8 is specified by default.
Note : This criterion is disabled when a value of 0 is specified.
Specifying this correlation as Rho (ρ), sets the radius for SAS PROC FASTCLUS equal to:
where MeanUSS is the average of row-wise uncorrected sums of squares.
